Phase-Locked Loop and Fuzzy Sliding Mode Control of Induction Motors
感应电动机锁相及模糊滑动模控制

Several control methods have been adopted in speed control systems of induction motors.Sliding mode control can decouple torque and flux in the inner loop. Phase Locked Loop is applied in the outer loop to acquire high precision. And Fuzzy Sliding Mode Control is added during the dynamic stage. So the system's transient performance and robustness are ensured.
