Abstract

The development of industrial in Indonesia is very fast. Many factories in indonesia don�t have the settlement of disposal place well, so they throw away production waste in along their place and it can pollute the system of river. To detect pollutan in the river, it�s made the simulation of river with constan flow. Therefore, it�s designed three phase speed control system by using three phase inverter circuit which has output voltage 220 Vac and frequency range between 10 Hz�50 Hz. To get the best response of ultrasonic sensor the system is used PID controller. When frequency of inverter 50 Hz the line to line voltage measured 231,3 Volt and speed of motor 1459 rpm, where the input voltage of inverter is 298,5 Vdc. Response of water level�s gotten by testing ultrasonic sensor. Based on graphic of ultrasonic sensor response reading,it can find parameter of Kp 9.8, Ki 0.07, and Kd 6. After using the parameter of Kp, Ki, and Kd, system has rise time on 300 second, overshoot 200 second and steady state on 1600 second. Keyword :Microcontroller Atmega128, Inverter 3 Phase, Frequency
