The application of A.C. motor to servomotor is rapidly increased according to the recent advance of power electronics and digital control techniques. The induction motor is widely used in the industrial field for the variable speed and position control because of its simple structure and easy maintenance. In this paper, the speed of single phase induction motor driven by full bridge inverter is controlled by a PID controller under the condition of stepwise disturbance load changes, and the current characteristics of the system is investigated to look for the good properties of A.C. motor torque through the experiment. From the experimental results. it is confirmed that the speed of single phase induction motor driven by full bridge series inverter can be smoothly controlled by an analog PID controller.
