摘要

介绍了一种利用高速数字信号处理器通过测量定子数量来估计永磁同步电机转子位置和转速的新方法。该方法的基本思想源于利用永磁同步电机的显著特性。利用基于pc机的SIMNON程序对带位置估计器的永磁同步电机的矢量控制驱动器进行了仿真。仿真结果表明，带位置估计器的机器性能与带位置传感器的机器性能基本一致。由于估计算法需要很少的指令，如乘法、加法和减法，因此它非常适合使用高速数字信号处理器的实时应用。

Rotor position estimation scheme of a permanent magnet synchronous machine for high performance variable speed drive

A novel method of estimating the rotor position and speed of a permanent magnet (PM) synchronous motor using a high-speed digital signal processor by measuring stator quantities is described. The basic idea of this method stems from exploiting the saliency characteristics of a PM synchronous machine. A complete vector control drive of a PM synchronous machine with position estimator has been simulated using the PC-based SIMNON program. The simulation results show that the performance of the machine with position estimator is in close agreement with that of a position sensor. Since the estimation algorithm needs few instructions, such as multiplications and additions and subtractions, it is well suited for real-time application using a high-speed digital signal processor.<>
