摘　　要：基于转子磁场定向坐标系下的永磁同步电机(PMSM)模型,提出一种PMSM的模型参考自适应反步控制方法.该方法采用线性参考模型来给出控制系统的性能规范,通过定义虚拟控制和选择适当的Lyapunov函数来保证整个系统的稳定性,进而导出系统控制律及参数自适应律.系统可在电机参数变化和负载扰动的情况下,渐近跟踪参考模型给出的转速和定子电流信号.仿真结果证实了该方法的有效性.Based on the model of permanent magnet synchronous motors （PMSM） in field-oriented coordinates, a model reference adaptive backstepping control method of PMSM is proposed. A linear reference model is used to give the performance specification of the control system. Then, by defining the virtual control and selecting the proper Lyapunov function, the stability of the drive system can be guaranteed. The control law and parameter updating law are derived step by step. The system can asymptotically track the rotor speed and flux reference signals generated by the reference model under parameter uncertainties and load torque disturbance. Simulation results illustrate the effectiveness of the proposed approach.
