摘要

提出了一种由电压源空间矢量调制(SVM)逆变器驱动的异步电动机无速度传感器直接场定向控制(DFOC)方法。该方法基于扩展卡尔曼滤波(EKF)，仅从定子数量、电流和线路电压估计转子速度。将估计的速度作为DFOC方案的反馈信号，实现无速度传感器矢量控制。讨论了该方法的原理以及在DSP开发系统上实现该方案的实际考虑。仿真结果表明，该方法具有良好的性能和鲁棒性。

EKF based speed sensorless vector control of an induction machine

This paper presents a method for speed sensorless direct field oriented control (DFOC) of an induction motor (IM) driven by a voltage-source space vector modulation (SVM) inverter. The approach in this study is based on an extended Kalman filter (EKF), which estimates the rotor speed from only stator quantities, currents and line voltages. The estimated speed is used as the feedback signal for the DFOC scheme to achieve the speed sensorless vector control. A principle of this method and the practical considerations for implementing the proposed scheme on a DSP development system are discussed. Simulations results demonstrate a good performance and robustness.
