Single Phase Induction Motor Speed Control Using Frog-Jumping Algorithm Technique

An adjustable speed single phase induction motors are widely used in domestic applications and industries. It is difficult to get such a single phase induction motor practically. The present work deals with the analysis and design of a speed control for a single phase induction motor . There are several methods which may be used to control the speed such a motor : voltage control ,frequency control and a voltage to frequency control, which is widely used in this application . Most of the previous methods are suffering from certain problems ,e.g narrow speed range , starting problems , the low efficiency of the motor. Here a novel method is suggested to use for controller design . the suggested method computed the best values for the frequency and the voltage for any desired reference speed . The simulated open-loop system as well as the closed-loop one are analyzed and the result show that the actual speed is tracking the desired speed and the deference between the reference speed and actual is acceptable (less than 2%).
