Main objective of this project is to study the speed control method of single-phase induction motor. Theoretically, there are several ways to control the speed of the motor. The methods are: varying rotor resistance, changing input voltage, changing number of pole and changing electrical frequency. The best way to control the speed of the motor is to control the frequency of the voltage supplied. The Pulse Width Modulation (PWM) technique is used in order to do so. The implementation of this PWM will not affect the performance of the motor and no adjustment on the motor stator is required. The project was done in two phases. In phase one, the characteristics of the motor, technique to control the motor's speed and PWM technique were studied. The second phase covered the development of the simulation model in Matlab/Simulink. The simulations were carried out and the results were analyzed. The simulation was done to test the speed control technique of single-phase induction motor. The motor was able be controlled according to the specific criteria to vary the speed by entering the desired speed value or desired electrical frequency. The acceleration and deceleration ramp function were also tested in the simulation. The characteristic of the 75% and 100% of full load can be observed in this simulation. For conclusion, the speed control method using PWM to control the voltage frequency has been studied, simulated and tested. It is proven that the technique can successfully control the speed of single-phase induction motor.
