Abstract

Abstract

Speed synchronization performance and anti-interference are important factors that affect the synchronous operation dynamic response and steady-state accuracy of dual Permanent Magnet Synchronous Motors’ (Dual-PMSMs). By introducing cross-coupling control as the framework, an integral sliding mode speed tracking controller based on an improved bi-power reaching method is proposed to reduce the speed error between two motors. A load torque observer is designed to bring the observed value into the Sliding Mode Control (SMC) reaching method that enhances the anti-disturbance performance of the system. Meanwhile, a synchronous controller is designed using a Fuzzy-Proportional-Integral-Derivative (FPID) control to improve the synchronization of the Dual-PMSMs. The results show that compared with the traditional PI algorithm as the target speed is 800 r/min, the proposed control method can decrease the two motors’ speed synchronization error from 25 r/min to 12 r/min under a no-load startup and reduce the speed synchronization error from 7 r/min to 2.2 r/min with sudden load torque, improving the synchronization and disturbance rejection.
