Abstract

Fakhruddin Mangkusasmito, Tsani Hendro Nugroho in this paper explain that One of the important control system in the manufacturing industry is the position control. Mainly in the Computer Numerical Control (CNC) machine, work-table motion control system is used to regulate work-table movements when the machine process a workpieces on it. On standard machines, work-table movements are two axes (X-Y), which is driven by a motor and lead-screw. The discussion in this research only focus on one axis assuming that the systems on both axes are the same and independent. In this research, MATLAB is used to describe the behaviour of the system and also to design appropriate control system in continuos system using state feedback linear controller such as pole placement , tracking system, full order compensator and reduced order compensator. The goal is to obtain a fast response with a rapid rise time and settling time to a step command, while not exceeding an overshoot of 5%. The specification are than a percent overshoot equal to1%, 0,05s settling time and 0,03s rise time. The performance of each control methods are simulated and analyzed to decide the best suit control method for the systems with such criteria. And the result verify that using tracking system controller method achieve such specification with 0% overshoot, 0,04s settling time and 0,028s rise time.

Abstract

Internal temperature of electric panel practically depend on the amount of power dissipation generated by the panel components and the outside temperature. If this equilibrium is not maintained then the internal temperature can increase too high beyond the working temperature limit for components so as to shorten the life of panel components. Generally, there are two fans installed to circulate the air inside the panel that operates at  fixed speed. In order to improve fan energy efficiency, it is necessary to add a control system that can adjust the fan speed based on actual panel internal temperature. Efforts to increase energy efficiency are realized using cheap hardware and easily available on the market, the ATMEGA 8535 microcontroller and LM 35 temperature sensor. The fan speed is normalized in percent units and expressed virtually using the Pulse Width Modulation (PWM) signal value calculated by the proportional control algorithm inside the controller. The experimental results show that the PWM value can vary with actual panel internal temperature. Using the time constant temperature asumption k1 = 0.2, k2 = 0.4, k3 = 0.2, k4 = 0.2 and experimental data, it was shown by calculations that there was an increase in energy efficiency by 40.8%.

Abstract

The identification system is a procedure to obtain a model of a system, then of the model will be validated to see the accuracy of the model is obtained, compared to the input-output results obtained from the experiments. In the identification system itself known two methods, the method of "non-parametric" and "parametric". On the other hand, DC motor is a type of motor that uses direct electric current to produce rotational mechanical energy and is widely used in various applications. In this study, input and output data acquisition will be performed on the Feedback brand DC motor, and the data will be processed so that the system model is obtained by the black box method. The data will then be processed with the help of MATLAB software. The input signal used in this experiment is Pseudorandom binary sequence (PRBS), which is used because it has a wide frequency range. The signal is generated by an arduino uno microcontroller. From the test results it was found that the validation of the non parametric system model with the correlation analysis method has a fitness value of = 83.19%, while the validation of the parametric system model with the least square ARX method has a fitness value of = 80.59%.

Abstract

Kebutuhan energi, terutama listrik di Indonesia, merupakan bagian yang tidak terpisahkan dari kehidupan sehari-hari masyarakat, sehingga listrik sangat dibutuhkan baik dari segi kualitas (kualitas dan keandalan) maupun kuantitas (kontinuitas distribusi). Diperlukan sistem proteksi untuk mempertahankan distribusi energi listrik sebanyak mungkin. Selain sistem proteksi, pengurangan area pemadaman karena gangguan dan pemeliharaan pada jaringan atau pada outgoing cubicle dapat dilakukan dengan manuver jaringan. Melakukan manuver jaringan dapat mengubah konfigurasi pada jaringan itu sendiri. Ini menyebabkan peralatan proteksi tidak berfungsi dengan baik sehingga keandalan jaringan setelah melakukan manuver akan berkurang. Penelitian ini mensimulasikan otomatisasi penggantian nilai pengaturan relai awal pada outgoing PMT dengan nilai cadangan ketika salah satu pengumpan harus dipadamkan karena akan dipertahankan. Pengujian menunjukkan ketika sensor membaca jumlah arus di setiap PMT melebihi nilai pengaturan awal, kontroler akan memerintahkan relai PMT untuk trip. Pada saat yang sama, jika LBS NO 1 atau LBS NO 2 ditutup, nilai pengaturan relai perlindungan awal pada PMT A akan secara otomatis diganti dengan nilai cadangannya, sehingga peningkatan arus beban tidak menyebabkan PMT A trip. Hal ini menunjukkan keberhasilan simulasi otomatisasi proteksi.Energy needs, especially electricity in Indonesia, are an inseparable part of people's daily lives, so electricity is needed both in terms of quality (quality and reliability) and quantity (continuity of distribution). A protection system is needed to maintain the distribution of electrical energy as much as possible. In addition to the protection system, the reduction of the blackout area due to disturbances and maintenance on the network or on the outgoing cubicle can be done by maneuvering the network. Performing network maneuvers can change the configuration of the network itself. This causes the protection equipment to not function properly so that the reliability of the network after performing the maneuver will be reduced. This study simulates the automatic replacement of the initial relay setting value on the outgoing PMT with a backup value when one of the feeders must be turned off because it will be maintained. Tests show that when the sensor reads the amount of current in each PMT exceeds the initial setting value, the controller will instruct the PMT relay to trip. At the same time, if LBS NO 1 or LBS NO 2 is closed, the initial protection relay setting value on PMT A will be automatically replaced with its reserve value, so that the increase in load current does not cause PMT A to trip. This shows the success of the protection automation simulation.

Abstract

Oil cooled power transformer has important role in the electricity distribution system. Its windings were immersed in oil as an insulating medium and also as a cooler. This oil would be heated up due to several things, the most significant was heat generated by winding’s power loss. The monitoring of oil temperature on the transformer was always done routinely every day to maintain its performance and health condition. IoT based measurements could improved efficiency and minimized manpower resources. To realize this the indirect non-destructive measurement method was proposed to estimate transformator’s temperature oil. It will corellate the oil temperature and body temperature through a constant calibration factor derived from calculations. Conducted experiment applied to specific existing transformator and followed by calculations resulted a calibration factor = 1.7749. The smallest average of estimated temperature error was lied in the range of 40 - 90 degrees Celcius.

Abstract

GY-521 MPU-6050 Module is a core module MPU-6050, which is a 6 axis Motion Processing Unit. This sensor can be categorized as an Inertial Measurement Unit (IMU) sensor, which utilizes measurement systems such as gyroscopes and accelerometers to estimate the relative position, velocity, and acceleration of an object. A common accuracy problem in using IMU sensors, including the GY-521 MPU-6050, is the drifting phenomenon. This phenomenon results in a deviation between the actual conditions (position, angular velocity) and the sensor readings. Drift is caused by the accumulation of errors that arise from calculating the integral of the acceleration. This study proposes a drift error correction method at the sensor output using the calibration of the calculation of the average offset error sensor and the sensor fusion method between the information obtained from the gyroscope and accelerometer in the module, the tests were carried out using the Arduino Uno microcontroller. From the test results, it is found that the combination of the initial system calibration implementation and the use of the fusion sensor concept can provide better performance with the MSE analysis results for the roll position of 0.0029o and the pitch position of 0.0047o and the drifting error rate at the yaw angle position of 0 0082o / second or down 62.72%.

Abstract

This research has succeeded in making a diode forward bias characterization test device using the ADC and the internal DAC of the ESP32 microcontroller. The output voltage of the DAC is added by 2 times the LM358 non-reversing op-amp amplifier circuit. So that the test results of the DAC output voltage can reach a maximum value of 6.3 volts as a source of variable DC power supply for the diode forward bias characteristic test circuit. Diode forward bias characterization testing is carried out through the interface of an Android smartphone with a WiFi network and a forward bias characterization curve is obtained which has a value and shape almost the same as the manual test. Testing the diode forward bias characterization using this application is faster than using manual measurements with a multimeter measuring instrument. Based on tests carried out using the Android smartphone application for 3 times, it was obtained an average time of 30 seconds, while manually using a measuring instrument obtained an average time of 657.7 seconds.
