| 摘 要： | 针对异步电机无速度传感器控制系统，提出了一种基于滑模控制(SMC)的改进型异步电机全阶磁链观测器方法。该方法利用全阶磁链观测器来辨识转速和估计转子磁链，并设计出滑模转速控制器来代替传统PI转速控制器，不仅能减小低中高速时系统转速动态响应的超调量，还能缩短进入稳态值的时间，增强系统的鲁棒性。仿真结果表明该算法的有效性。

| Abstract: | Aiming at the sensorless control system of asynchronous motor, an improved asynchronous motor full-order flux observer method based on sliding mode control is proposed. This method uses a full-order flux observer to identify the speed and estimate the rotor flux, and a sliding mode speed controller is designed to replace the traditional PI speed controller. The algorithm can reduce the overshoot of the dynamic response of the system speed at low,medium and high speeds, shorten the time to enter the steady state value, and enhance the robustness of the system. Simulation results show the effectiveness of the algorithm. |
