摘要
针对永磁同步电机传统PID矢量控制方式无法实现d、q轴电流完全解耦控制的问题,运用反馈线性化理论实现永磁同步电机转速和d轴电流解耦。针对反馈线性化导致的鲁棒性下降问题,利用滑模控制方式提高系统鲁棒性,引入新型双幂次趋近律,建立永磁同步电机反馈线性化滑模控制系统。使用Simulink对控制系统进行仿真分析,并与传统PID控制方式对比,仿真结果表明,该新型控制系统具有稳态精度高,动态响应快,抗扰动能力强等优点。
The traditional PID vector control of permanent magnet synchronous motor(PMSM)can not realize the complete decoupling control of d and q axis currents.The feedback linearization theory was used to decouple speed and d-axis current of PMSM.To solve the problem of robustness degradation caused by feedback linearization,the sliding mode control method was used,and a novel double power reaching law was introduced to establish a feedback linearized sliding mode control system for PMSM.The system was simulated by Simulink and compared with the traditional PID control method.The simulation shows that the new control system has the advantages of high steady-state accuracy,fast dynamic response and strong anti-disturbance capability.
