摘要
为改善永磁同步电机无速度传感器控制系统对参数变化和负载扰动的鲁棒性,将滑模变结构控制引入到模型参考自适应系统中,提出一种基于变结构模型参考自适应系统的永磁同步电机转速辨识方法。理论分析和仿真结果表明,该方法具有良好的动静态性能,比传统模型参考自适应系统具有更高的估计精度,对参数变化和负载扰动有更强的鲁棒性,且算法简单,易于实现。
In the sensorless control of permanent magnet sychronous motor（ PMSM）, to improve the robustness and load disturbance, the slidng mode control （SMC） into the model reference addptive system （MRAS） was intro- duced. Based on the traditional MRAS, a sliding mode MRAS speed estimation method was proposed. Theoretical analysis and simulation results showed that the proposed sliding mode-model reference adaptive sensorless control of permanent magnet synchronous motor has higher estimation accuracy and more robust compared to traditional MRAS, and easy lo implement.
