Speed Control of Three Phase Induction Motor Using Universal Bridge and PID Controller

Abstract

In simpler terms, techniques to control speed are very important in a system that can change how fast it goes. A device called a three-phase voltage source inverter can give the system different levels of voltage and frequency power. This article explains how to use a device called a universal bridge and a method called pulse width modulation to change the speed of a motor that runs on a special type of electricity called three-phase voltage. The motor is called an induction motor. A machine was made to control the highest amount of electrical power in a device called a voltage source inverter. Matlab/Simulink is used to study the speed control systems and see how well they work if they are open or closed. The simulation showed that the speed controller works well and can make the induction motor work better.
