基于滑模扰动补偿永磁同步电动机PWM预测控制
PWM Predictive Control of Permanent Magnet Synchronous Motor Based on Sliding Mode Disturbance Compensation
摘要
Abstract
To solve current steady-state error and oscillation caused by motor model mismatch and parameter perturbation in PWM current predictive control of the permanent magnet synchronous motor(PMSM),a PWM current prediction control algorithm based on sliding mode disturbance compensation was proposed. Based on the traditional PWM current predictive control,the parameter perturbation was introduced into the motor voltage equation,and the sliding mode disturbance compensators of d,q axis were constructed to correct the current loop output voltage in real time and suppress the influence of the motor parameter changes on the control system. The stability of the proposed algorithm was verified by Lyapunov theory. The simulation results show that the proposed method can achieve fast tracking control and improve the stability of PWM predictive control system to internal and external disturbances.关键词
