摘要

本文对永磁同步电动机无传感器控制的稳定性进行了分析。在无传感器控制方法中，通过测量定子电流来估计电机的转速。为了估计电机的速度，我们使用模型参考自适应系统(MRAS)方法作为观测器。采用积分比例(IP)调速控制器对系统进行控制。将非线性系统线性化，并以状态空间形式表示。为了确定系统的稳定性，必须求出矩阵的特征值。利用博德稳定性判据和根轨迹分析了系统的稳定性。

Stability analysis of MRAS speed sensorless control of permanent magnet synchronous motor

This paper presents stability analysis of Permanent Magnet Synchronous Motor (PMSM) sensorless control. In the sensorless control method, the stator current is measured to estimate the speed of the motor. To estimate the speed of the motor, we use Model Reference Adaptive System (MRAS) method as an observer. The Integral Proportional (IP) speed controller is used to control the system. The nonlinear system is linearized and expressed in state space form. To determine the stability of the system, it is necessary to find the eigenvalues of the matrix. The stability of the system is also analyzed using Bode stability criterion and Root Locus.
