滑模变结构在PMSM DTC中的应用

The Application of Sliding mode control theory to PMSM DTC

在传统的永磁同步电机直接转矩控制系统中常采用PI调节器作为速度调节器,本文提出一种以优化指数滑模变结构控制器替代传统直接转矩控制系统中的速度PI调节器并进行仿真实验,结果显示该系统保留了直接转矩控制的优点,在提高了系统的动态性能的情况下,减小了转矩脉动,仿真和实验结果验证了系统具有良好的鲁棒性。

In a traditional permanent magnet synchronous motor direct torque control system are often used as a PI regulator speed regulator,the paper proposes a sliding mode controller optimized index instead of the traditional direct torque control system of the speed PI regulator simulation and experimental results show that The system retains the advantages of direct torque control in improving the dynamic performance of the case and reduce the torque pulse,simulation and experimental results show the system has good robustness.
