Abstract

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.
