摘　　要：永磁同步电动机拥有能耗低、稳定性高等优点,在现代电梯驱动系统中已经得到广泛应用。随着电力电子技术的发展,永磁同步电动机控制技术也得到了飞速发展。现如今,永磁同步电动机变频控制方法也已经从最为简单的恒压比控制(V/f)发展为系统更加稳定的矢量控制(FOC)和直接转矩控制(DTC)。同时为优化永磁同步电动机设计、节约制造成本、提高永磁同步电动机运行稳定性,更具经济效益和实用价值的永磁同步电动机的无位置传感器控制方法已经成为研究的重点。The permanent magnet synchronous motors have the advantages of low energy consumption and high stability, and have been widely used in modern elevator drive systems. With the development of power electronic technology, the control technology of permanent magnet synchronous motor has also been developed rapidly.Nowadays, the frequency conversion control method of permanent magnet synchronous motor has also developed from the simplest constant voltage ratio control(V/f) to the more stable system vector control(FOC) and direct torque control(DTC). At the same time, in order to optimize the design of permanent magnet synchronous motors,save manufacturing costs, and improve the operation stability of permanent magnet synchronous motors, the position sensorless control method of permanent magnet synchronous motors with more economic benefits and practical value has become the focus of research.
