Induction motor vector control system based on anti-windup controller

In the induction motor indirect vector control system, because of its physical limits such as maximum current and voltage, the change of speed command or load would eventually cause the integral windup phenomenon and system performance degradation. A new anti-windup speed controller is proposed by combining the conditional integration and conditioning technique anti-windup. The conditioning technique is employed when the controller saturates. The simulation results proved the efficiency of anti-windup speed controller in the induction motor indirect vector control system.
