Abstract

Abstract: Speed control for three-phase induction motor with PID controller. The weakness of an induction motor is its disability to maintain the speed constantly during load changes; it will reduce the speed of induction motor. It needs a controller which enables an induction motor to maintain its speed in various set points and changing loads by determining system performance. The system is tested by referring settling point, rise time, delay time, time constant, and error state. The PID controller with 8,032 micro-controller can produce a good performance in following state: in starting phase, changing load torques, and achieving set point in t = 1.68 s, T_R = 2.30 s, T_S = 3.80 s, T_D = 1.56 s, 1.29% error steady state (% Ess), and 1.50 Newton of load. In quick response (in mil-second), the induction motor becomes more stable, while in plant response there is no overshoot because the motor has been tied by a power brake that acts as a load.
