摘要
针对内埋式永磁同步电动机,综述了近年来转子位置和速度估计的一些新方法,给出了这些方法的简单原理、优缺点及应用范围等,指出混合运用零速到低速和低中速到高速这两类方法是切实有效的。今后研究的问题仍然集中在包含零速时稳定低速驱动的实现和伴随转矩控制的稳定起动上。
This paper summarizes some new methods of estimating rotor position and speed for interior permanent magnet synchronous motor and introduces the simple principle, merits and disadvantages, the fields of application of these approaches etc. It is indicated that the hybrid application of two sorts of methods, which is zero-speed to low speed and low middle speed to high speed, is effective and practical. The research issues in future still be focused on implement of stable low speed drive involving zero-speed and stable start-up with torque control.
