一种双永磁同步电机滑模同步驱动控制方法
A sliding-mode control of a Dual-PMSMs synchronization driving method
摘要
Abstract
Speed synchronization performance and anti-interference are important factors that affect the syn-chronous operation dynamic response and steady-state accuracy of dual Permanent Magnet Synchronous Mo-tors'(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 im-prove the synchronization of the Dual-PMSMs.The results show that compared with the traditional PI al-gorithm 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 synchroniza-tion error from 7 r/min to 2.2 r/min with sudden load torque,improving the synchronization and disturbance rejection.关键词
