摘要本文在深入分析永磁同步电机数学模型的基础上,将滑模变结构控制应用于永磁同步电机控制系统中,根据永磁同步电机的数学模型,设计了一个滑模变结构控制器,用于估算电机转子位置和速度;根据磁场定向控制理论,利用估算的转子角度实现了无传感器矢量控制。实验结果表明,滑模变结构控制器对系统参数变化、外界环境的扰动以及内部的摄动具有很强的鲁棒性,能够在全频率范围内追踪实际信号,实现对转轴位置的观测。 Base on the idea of sliding mode observer, a new method of designing the sliding mode observer for PMSM control system is proposed. The algorithm for estimating position and speed of PMSM is presented, which is simple in structure and easy to be implemented by using a this observer. Experimental resuh showed that parameters computer. Sensorless field orientation control system is achieved by using the observer has good robustness to load disturbance and time varying
