Abstract :
The windup phenomenon appears and results in performance degradation when the proportional-integral (PI) speed controller output is saturated for the motor drive system. A new antiwindup speed controller is proposed to improve the speed control performance of the motor drive system. Based on the internal model control (IMC) method, the proposed controller is designed, the parameters of which are expressed directly in the system parameters and the desired closed loop bandwidth. This simplifies the speed controller design procedure, and trial-and-error can be avoided. Some simulated results are provided to demonstrate the effectiveness of the proposed controller
