Abstract

This paper presents a study carried out on maximizing energy harvesting of wind turbines. One way of improving the output power of the wind turbines is by optimizing the power conversion coefficient. The power conversion coefficient factor is expressed as a function of the wind turbine blade tip speed ratio and the turbine blade pitch angle. Optimization of the wind turbine generator output power is done by considering the effects of variations of wind speed, blade tip speed ratio, and pitch angle. An intelligent soft computing technique known as an adaptive neuro-fuzzy inference system (ANFIS) with a fuzzy logic controller for blade pitch actuator was applied to optimize the generator output power. The simulation result showed that the power conversion coefficient of 0.513 is achieved. The study was verified by using real-time wind speed data of Adama II wind farm in Ethiopia and specifications of the Gamesa G80 horizontal axis wind turbine generator unit by MATLAB software. Accordingly, a promising and satisfying improvement in power harvesting capacity is obtained. The output power of this generator is improved by 9.47% which is by far better result as compared to the existing literature.Keywords: optimization tool, pitch angle, tip speed ratio, wind energy conversion coefficient.

Abstract

Medicines should be stored in a room at a suitable temperature because the condition of temperature affects the quality of the drug. Improper storage procedures may result in the drug being unable to cure effectively and cause drug damage which results in losses for pharmaceutical industry companies and patients. Therefore a controller for temperature is needed in the room so that it is constantly under the rules of room temperature for drug storage, which is 25 degrees Celsius. The following paperwork presents a simulation controller between PI controller and PI-Fuzzy logic controller in adjusting the voltage to match the set of points. The fuzzy logic controller automatically searches Kp value so the voltage output of the converter matches the desired set of points. The converter used is a synchronous boost converter as a voltage regulator and Peltier as a DC load which functions as a cooler. In this research, the system using PI controller was able to adjust the voltage to match the set point 60V with KP is 0.14089, Ki is 125.6738, and the settling time is 0.016 s. While the system using PI-Fuzzy logic controller, it was able to adjust the voltage to match the set point 60V with Kp is 0.08112, Ki is 125.6738, and settling time is 0.014 s. It can be concluded that the PI Fuzzy controller can find the KP value automatically and reach the desired set point. Keywords: peltier, PI cotroller, PI-fuuzzy logic controller, synchronous boost converter

Abstract

Currently, research in face recognition systems mainly utilized deep learning to achieve high accuracy. Using deep learning as the base platform, per frame image processing to detect and recognize faces is computationally expensive, especially for video surveillance systems using large numbers of mounted cameras simultaneously streaming video data to the system. The idea behind this research is that the system does not need to recognize every occurrence of faces in every frame. We used MobileNet SSD to detect the face, Kalman filter to predict face location in the next frame when detection fails, and Hungarian algorithm to maintain the identity of each face. Based on the result, using our algorithm 87.832 face that must be recognized is reduced to only 204 faces, and run at the real-time scenario. This method is proven to be used in surveillance systems by reducing the computational cost.Keywords: Hungarian algorithm, Kalman filter, multiple face tracking, video surveillance system.

Abstract

Mint plants provide many benefits in everyday life ranging from enhancing aroma and taste in food and beverages, medicine, perfume, cosmetics until as antibacterial, anti-virus and fungal drugs. Mint is an herbal plant that comes from subtropical areas. When it is planted in tropical areas, mint will grow to creep and will not flowering, so it is cultivated in tropical areas such as in Indonesia by using vegetative methods, namely stem cuttings. This raises problems including shoot growth that takes a long time, regular maintenance, and the need for additional nutrients to support the growth of stems and leaf buds. This study aimed to design and build an automatic integrated care control system for mint cultivation. The integrated system that was built includes the provision of nutrition for young coconut water at a dose of 10 milliliters which is flowed on the surface of the mint plant stem cuttings with the frequency of nutrition twice in a day at 8 AM and 4 PM. The second system that was built was automatic watering carried out on 350 milliliters of mint soil media every morning and evening at 7 AM and 5 PM. After testing, the results showed that the detector could work well in reading the activation time of the nutrient pump and sprinkler pump. There were time differences of 4 milliseconds in the delivery of nutrition testing, while in the delay test for watering the planting medium there was a time difference of 70 milliseconds from the time set on the RTC. Overall, the tools that have been made are adequate to assist farmers in cultivating the mint plant, starting from the process of watering the stem cuttings to providing nutrients to accelerate and increase the growth of leaf buds.Keywords: automatic, humidity sensor YL-69, microcontroller, mint leaves, nourishing system, RTC, watering system.

Abstract

Nonholonomic Mobile Robot (NMR) is a mode of transportation that is widely used in industry. To achieve flexibility in carrying out its duties, an adequate control system is needed in transportation arrangements so that it is used as an object of research. The problem that is taken in this study is about tracking control for several reference trajectories with input constraint. To solve this problem two controllers were designed, kinematics controller and dynamics controller. Kinematics controller is designed so that the additional speed converges to the desired speed by adjusting the gain value. Dynamic controller is designed using  performance to overcome the input constraint and the Lyapunoc inequality is soleved by Linear Matric Inequalities (LMI) so the gain state-feedback can be obtained. Simulation results show that the designed controller is capable of tracking according to the reference trajectory with input constraint given.Keywords: ????∞ performance, input constraint, linear matrix inequalities, NMR.

Abstract

Solar energy is a renewable energy. Solar energy can be utilized using solar panels. The use of solar panels mostly uses static or silent methods. The static method on solar panels cannot produce optimal electrical energy. This is because the intensity of sunlight received by solar panels is less than optimal. So that the resulting electrical energy is not optimal. Therefore we need a system that can control solar panels automatically. this system must also be able to follow the direction of movement of sunlight. This study discusses the dual axis solar tracker using smart relay-based astronomical methods. This study adjusts the angle of the solar panels to determine the movement of the sun. This study uses a smart relay to regulate the rotation of the DC motor (Linear Actuator) and the motor power window which functions as a driving force for solar panels. Astronomical method is used for tracking sunlight. This method is based on the position of the sun according to the lunar calendar. This method uses an angle sensor in the form of a variable resistor for elevation and a rotary encoder as an azimuth angle sensor. The results obtained from this study are the optimal electrical energy output from solar energy. Keywords: renewable energy, dual axis, solar tracker, solar panel, astronomical method

Abstract

In this paper, the acoustic signal within an audio sonic range emitted by partial discharge (PD) in an oil-filled cylindrical tank was investigated. The PD was generated by point-to-flat electrodes subjected to a high-voltage DC. The PD source location, installation method, and sensor microphone, as well as the electrode gap distance, were varied. Subsequently, acoustic waveforms and their frequency spectrum, as well as the PD current, were analyzed. The results showed that transient acoustic signals indicated the emergence of PD. The acoustic sensor attached to the outer wall of the tank (contact type) was more sensitive than the sensor that had a distance from the tank (non-contact type). Sensor contact type acoustic signals placed parallel to the location of the PD source provided a more accurate signal form compared to those set nonparallel to the frequency spectrum, which was relatively flat. A closer electrode distance caused the duration, acoustic signal amplitude as well as the currents to be more considerable. For the identical variable, the acoustic signal form was not related to the current signal despite the same signal duration. Besides, locations of sources of the PD notably influenced the signal form, but it did not apply for the current signal.Keywords: acoustic, audio frequency, fast Fourier transform, high-frequency current transformer, oil transformer, partial discharge

Abstract

The problems of using solar panels include the power and efficiency that can be achieved by solar panels during conditions where the surface of the solar panel is covered by shadows, because the performance of the solar panels is affected by the amount of sunlight received and the temperature of the solar panels. Then, a solution appears to overcome the problem, called Maximum Power Point Tracking or a technique to get the maximum output power from solar panels. Initially, MPPT worked with conventional methods, one of which was Perturb and Observe. Furthermore, the MPPT method on solar panels continues to develop to solve problems during partial shade conditions. The development of this conventional method is called the metaheuristic method, an example of which is the Cuckoo Search Algorithm method implemented in this research. This method is characterized by the Levy Flight equation in generating duty cycle values so that it can reach the maximum peak power of solar panels. The system built in this research is also supported by the highly efficient Interleaved Boost converter. Based on simulation results show that the power that can be generated by the MPPT Cuckoo Search Algorithm is higher than the MPPT Perturb and Observe, which is 121.23 W compared to 72.38 W.Keywords: automatic, humidity sensor YL-69, microcontroller, mint leaves, nourishing system, watering system, RTC.

Abstract

Battery is one of the important components in the development of renewable energy technology. This paper presents a method for estimating the State of Charge (SoC) for a 4Ah Li-ion battery. State of Charge (SoC) is the status of the capacity in the battery in the form of a percentage which makes it easier to monitor the battery during use. Coulomb calculations are widely used, but this method still contains errors during integration. In this paper, SoC measurement using Open Circuit Voltage Compensation is used for the determination of the initial SoC, so that the initial SoC reading is more precise, because if the initial SoC reading only uses a voltage sensor, the initial SoC reading is less precise which affects the next n second SoC reading. In this paper, we present a battery management system design or commonly known as BMS (Battery Management System) which focuses on the monitoring function. BMS uses a voltage sensor in the form of a voltage divider circuit and an ACS 712 current sensor to send information about the battery condition to the microcontroller as the control center. Besides, BMS is equipped with a protection relay to protect the battery. The estimation results of the 12volt 4Ah Li-ion battery SoC with the actual reading show an error of less than 1%.Keywords: battery management system, modified coulomb counting, state of charge

Abstract

Unmanned Surface Vehicle (USV) is an unmanned ship that is controlled through a remote control system (manual) or automatic control system (autopilot), move due to the thrust force from thruster machine and can turning due to the deflection angle of rudder. The USV path planning system becomes an important task so that the ship can make the global trajectory with the minimum travel distance according to the desired navigation while at the same able to avoid various obstacles from local dangerous situations that have the potential for collisions. To be able to do dynamic USV path planning, the Genetic Algorithm method with a sliding curve guidance system and PID MRAC controller is used. The use of this method gives smooth ship track performance with shortest distance in a 400x400 square meter map with static and dynamic obstacles. In a dynamic environment, the path replanning process that takes place in 0,98 seconds is able to find a new path that does not collide the obstacles. For the purposes of algorithm validation, the simulation is performed using MATLAB software with real ship parameters of 6 meters length USV.Keywords: dynamic and static obstacle, genetic algorithm, guidance system, path planning, PID MRAC, sliding curve, USV.
