摘　　要：速度辨识一直是永磁同步电机无速度传感器控制系统中的一个核心问题,本文以永磁同步电机本身为参考模型,变换数学模型构造并联模型,并由转矩和转速的基本的机械运动方程和转矩方程推导出速度辨识率,结合模型参考自适应控制理论得到速度辨识方案。本方案控制过程简单,对电机参数不敏感,并将其应用在永磁同步电机矢量控制系统当中,仿真得到的结果验证了本方案的正确性和可行性,同时,与基于POPOV理论的模型参考自适应方案的仿真结果进行比较,分析本方案的优劣。The speed identification is the core question of the PMSM speed-sensorless control system,Starting form the mathematical mode of the PMSM,the adjustable model is built,therefore,the self-adaptation principle of the rotating speed is deduced by the mechanical motion equation and the torque equation,the new speed identification method is proposed based on MARS.The control process of the method is easy and is not sensitive to the parameters of the PMSM,this methods is applied in the vector system,method of this paper is testified Correctness and feasibility by the simulation results,therefore,the methods is comparison with the method of MARS based on the popov stability theory,then analyzing advantages and disadvantages of the method.
