We have already proposed a new anti-windup algorithm for Induction motors, and it regulates the motor speed smoothly and stably. This paper applies the proposed algorithm to the speed servo system for PM motor. However, the actual motor speed becomes smaller than it speed reference due to the field forcing caused by d-axis voltage saturation. Therefore, this thesis proposes a new anti-windup control scheme that is avoids the field forcing operation on condition of voltage saturation for a PM motor. The experimental results show that the proposed speed srevo system regulates a motor speed smoothly and stably.
