Abstract

The air distribution process is still using the manual method, namely by using human power to activate and deactivate the distribution pump and use the average demand graph as a reference. This results in irregular air distribution. Therefore we need a control system on the distribution of the pump that can work automatically to maintain air distribution according to the level of customer needs. One of the most important parts of a water pump is the drive in the form of an electric motor. One type of electric motor that can be used is a BLDC motor. The BLDC (Brushless Direct Current) motor is a development of the DC motor, where in the commutation process it uses electronic commutation so that there are no mechanical problems, and interactions. The use of a BLDC motor requires a control system to regulate its speed. One of the methods that can be used is using a PID controller. PID can improve motor response by producing a fast and smooth response and small overshoot, but the PID controller cannot be applied to non-linear loads, while BLDC motors have a multi-variable, non-linear system, and can easily be affected by parameter variations and disturbances. If this controller is still applied then the system response to stable conditions will be quite long and cause the motor to have poor performance. In this study, a controller was developed by combining PID controller with Fuzzy Logic Control. Fuzzy logic control produces additional parameters for each PID parameter controller. Variations of the FLC output make thecontroller implicitly adjustable. It is hoped that in this study, a response system will be obtained that has a high steady state level with a fast settling time.Keywords: BLDC Motor, PID Controller, Fuzzy Logic Control, Steady State

Abstract

In this study, positive ions were generated from the gas ionization process of tetrafluoroethane (R134a) using a high electric field. The high field is generated at the plate needle electrode array in a gas environment of tetrafluoroethane. The highest field occurs at the needle tip and the ionization process occurs around the needle tip. Each ionization of tetrafluoroethane gas produces one electron and one positive ion. To bombard the plate electrode, positive ions must move from the tip of the needle to the plate electrode. The needle electrode must be supplied with DC voltage of positive polarity while the plate electrode is grounded. The results showed that the positive ion bombardier effect on the physical charactertistic of the aluminum plate depended on the value of the kinetic energy of the ions when it hits the surface of the plate. The longer the free path of the positive ion, the greater the speed and kinetic energy of the ion when it strikes the plate electrode.Keywords – aluminum plate, ion bombardment, positive ion, tetraflouroethane

Abstract

The iodine clock reaction is when two clear solutions are mixed, producing another clear solution. After a while, the solution will instantly turn dark blue. The time for iodine clock reaction to change color can be used as a timer for the stoping mechanism on a chemically powered car prototype in Chem E Car competition. This temperature conditioning system aims to reduce the error of the iodine clock reaction time by adjusting the temperature to remain constant before being injected. In this study, the DS18B20 sensor was used to measure the solution temperature and DHT11 sensor to measure the ambient temperature. The OLED display used to showing sensor reading data. This system is designed to control the temperature of the solution to reamin constant with a setpoint range from ambient temperature to 50°C using PID control with Cohen-Coon tuning method. Parameter value obtained from this Cohen-Coon tuning method are Kp=10,25119, Ki=0,01754, Kd=780,66828. The actuator uses in this system are PTC heating element as a heater and DC fan as a cooler. The DS18B20 sensor readings and the control process are processed by Arduino Uno while the DHT11 readings and monitoring system are processed by

Abstract

The iodine clock reaction is a chemical reaction that consists of two different colorless solutions mixed into one container to produce a colorless solution and a few moments later the solution turns dark blue. This color change is used as a timer for the stopping mechanism for the chemical-powered car prototype in the Chem E Car team of Universitas Brawijaya. The injection syringe used to inject the iodine clock solution can affect the reaction time of the iodine clock solution due to the difference in pressure at the time of injection so the mixing speed varies. The injection system of iodine clock solution aims to reduce the error of the reaction time of the solution so that it becomes more constant. The system is also equipped with the Internet of Things (IoT) concept which aims to monitor the state of the iodine clock solution such as the temperature of the solution because the competition time is quite long, about 10 hours so that the iodine clock solution must be monitored while not in use. This study uses the YF-S401 sensor as an indicator of the volume of the iodine clock solution. In addition, the system uses an actuator, namely a solenoid valve as a valve for the ex

Abstract

Air pollution from motor vehicle fumes has become a big problem for the environment. The existence of electric vehicles is an effort to reduce the problem of air pollution. However, electric vehicles that use battery resources have a weakness in battery lifetime. To overcome this, we need a system where the battery life when used so as not to run out quickly, namely with a regenerative braking system. Simulation of the regenerative braking system for controlling a DC motor based on fuzzy-PID auto-tuning is a simulation of the regenerative braking system using a bidirectional DC-DC converter and controlling it using auto-tuning fuzzy-PID. This system simulation aims to obtain appropriate control with the system and determine changes in the SOC value of the battery from the resulting regenerative braking. From the system simulation results, it can be seen that the actual speed of the DC motor and changes in the SOC value of the battery can be seen by knowing the value of the performance parameters of the controls made.
