摘　　要：定子磁链观测器是磁场定向矢量控制的关键部分,在定子磁链定向的旋转坐标系下,采用低通滤波建立定子磁链观测器。用Psim软件对该模型进行仿真,用数字信号处理器进行硬件实现。仿真波形和实验结果表明该定子磁链观测器模型具有较高的系统稳定性和鲁棒性,具有一定的理论和实际应用意义。Stator flux observer is a key element of the magnetic field oriented vector control, A model of stator flux observer was established based on low pass filter in the stator flux oriented rotating coordinate system. The simulation and experiment results showed that this model had high stability and robustness and was useful in both theoretical and practical application.
