Abstract

This paper is to present the evaluation of a TiNi Shape Memory Alloy (SMA) spring as actuator for the gripping manipulation. The SMA spring employed was a TiNi tensile spring which has a diameter of 50 mm wire and 350 gram hanging mass. The gripper fabricated consists of two fingers and each finger is actuated by the SMA spring. The total angular displacement of the gripper is 300. The power consumptions, the movements and force generations experimentations have been conducted. The DC signal and PWM signal with 12, 12Hz, 25Hz, 125Hz, 250Hz and the 1150Hz have been employed for driving the SMA. The experimental results indicated that the 125Hz of PWM signal was likely to be had a better performance than the other signals. The 125Hz PWM signal generated faster movement, lower power consumption, and constant rate of force. In this study, closed-loop control for gripping manipulation was also conducted. The close loop controller used is PID controller. The Ziegler-Nichols method has been used to predict the optimal gain of the controller, but the best performance was determined by experimentally tuning of the gains. The experimental results indicated that the PID controller is likely to be reliable controller for gripping manipulation of the SMA spring. To obtain the better performance, it is important to consider the SMA cooling responses and the long time of retain in certain position of the gripper.

Abstract

Shape Memory Alloy (SMA) is emerging actuator for micro and nano application which is interesting to be developed. This paper presents the evaluation of close-loop controller responses of the TiNi SMA spring based gripper by introducing lag, lead and lag-lead compensator. A SMA spring has a diameter of 50 mm wire and 350 gram hanging mass. The driver of the SMA actuator uses pulse width modulation (PWM) signal and it is tested by varying frequencies and duty-cycles. The applied frequencies in this study are 12, 25, 125, 250 and 1150 Hz. Lab-View and DAQ-Card is used as a controller, interfacer and data recorder of the system. The fabricated gripper consists of two fingers and the total angular displacement of the gripper is 300. In advanced application, the experiment coversSMA open loop and close-loop system. The SMA response indicated that the rise-time and the steady-state error of the cloop-loop are shorter and lower than open-loop controller.

Abstract

Today, DC Microgrid gain more attraction due to increasing electronic digital devices application such smart-phones, smart-tvs, and other digital apparatus which are operated in DC form. In the common grid, the electric power from AC source is converted to DC voltage for powering the digital devices as load. Hence, there are power conversions from AC-DC and potentially loss energy during conversions. DC Microgrid consisted of sources, loads, distribution lines and energy storages. In small capacity DC Microgrid, the stability of the system is vulnerable by dynamic load change. During load demands fluctuations, the DC Microgrid voltage is also dynamically fluctuated and can reach over the designated rate. To solve this problem, the PID controller is introduced in the DC-DC converter for maintaining the voltage rate at designated value regardless the load demands. In this paper, the DC Microgrid is consisted of photovoltaics as DC sources, XL-6019 as DC-DC converter, Arduino as controller, voltage and current sensors, distribution lines and loads. The proposed method is evaluated via experimental results. The responses of the proposed method in the DC Microgrid system are presented, evaluated, discussed, and compared between with and without applied method. The experimental results indicate that the proposed method has ability to reduce the voltage profile fluctuations during load demands changes and in short time.

Abstract

Currently the industrial world continues to experience development, especially industries engaged in manufacturing. Product development by manufacturing companies is a must to meet consumer needs. One of the most efficient ways to develop these products is to use a 3D printer. The 3D printers on the market use the RAMPS 1.4 control board with the marlin firmware which is open source, while the 3D printers made use of the Arduino as the control system. This 3D printer has the ability to print straight lines with the Matlab application as an application to give commands to print. To get maximum results, it is necessary to prepare and test to get the appropriate parameters. Based on the testing of the tools that have been made, the 3D printer can function sufficiently with parameters such as nozzle temperature in the range of 150 ℃ and the distance between the nozzle tip and the print bed of 0.25 mm. The 3D printer that has been made has an accuracy rate of ± 9.4 mm with a resolution of 0.16 mm and a repitability of 0.2 mm.

Abstract

The output of photovoltaic is highly dependent on the intensity of sunlight. When the sunlight intensity received by photovoltaic matches or more than the specified, the photovoltaic can produce the maximum output according to the specifications. However, if the intensity is less than specification, the photovoltaic output will be less than expected. This can happen on cloudy days or in the morning, evening or night. Meanwhile, load electric power requirements may varies, it does not depend on time or weather. So that at that time the supply of electrical power needed by the load must be supplied by other energy producer, such as battery. Conversely, when photovoltaic generate maximum electrical power or more than the load requirement, more electrical energy can be stored by the battery. To be able to do this, a device must be designed that can regulate the amount of power output from the photovoltaic or battery. The photovoltaic or battery output power setting is adjusting the pulse width modulation (PWM) signal via a controller, namely Arduino MEGA 2560. This power setting works by utilizing a DC-DC converter, buck-boost converter type XL6019. Experiments were carried out experimentally and measured directly. Based on the measurement results, photovoltaic power has been able to supply the load's electrical power needs with a light intensity of 50% of the required specifications. The experimental results show that the proportion of power absorbed or discharged by the battery can be adjusted according to the photovoltaic output power to the load requirements.

Abstract

Robot is a set of mechanical devices that are programmed in advance to perform a task either with human supervision or control. Robot development continues to be carried out, one of which is swarm robots. Swarm robots are robots that work together like a collection of insects to do a job. The swarm robot consists of a leader robot and a follower robot that must communicate with each other for positioning. The communication system uses two xbee modules to get the Receive Signal Strength Indicator (RSSI) value in determining the distance between robots so that the follower robot can follow the movement of the leader robot. The method used is to test the communication between xbees and the comparison of the RSSI value to distance. Based on the results of the tests carried out, the results showed that the two xbees communicated well with each other and the RSSI values ​​obtained on the X-axis and Y-axis with the same distance did not change significantly.

Abstract

DC generator is a device that can change over mechanical energy into electrical energy. To be utilized as elecrical energy, a mechanical energy is required that comes from the revulotion of the rotor from a DC generator. The rotation of this DC generator is always changing or not constant. So that the power that comes out of the rotation of the rotor isn’t ideal. One way to maximize the power from the DC generator output is to find the maximum power point at the DC generator output. This final project has the objective of being able to discover the greatest point at the DC generator output, maximum power point tracking (MPPT) utilizing the Perturb and Observe (PO) algorithm. To find the maximum point in the final project, components are needed, namely a DC generator, Buck-Boost Converter XLSEMI 6019, connection sensor, INA219 Current Sensor, and a resistor as a load that will be controlled by Arduino Mega 2560. By using the PO algorithm this final project can be made to displays maximum power, maximum current, and maximum voltage.
