开发了采用永磁电机自适应观测器的无位置传感器控制系统。但是，提出的永磁电机自适应观测器设计方法在高速区域的特性已经存在问题。本文给出了一种自适应观测器的设计方法来解决这个问题。此外，本文提出了将永磁电机在静止坐标上的自适应观测器转换为旋转坐标上的观测器的技术。最后，我们通过实验证实了所提出的方法显示出良好的特性。
Position sensorless control system using adaptive observer of PM motor was developed.But the adaptive observer design method of PM motor suggested already has problem in a characteristic at a high-speed region.This paper gives a design method of the adaptive observer to solve this problem.In addition, this paper suggests technique to transform the adaptive observer of PM motor on a standstill coordinate into the observer on a rotational coordinate.Finally, we can confirm by an experiment thatproposed method shows good characteristics.
