摘　　要：提出了交流永磁同步电机多目标输出跟踪控制的一般方法,利用微分几何中的微分同胚转换,先将永磁同步电机的非线性模型转换为与之反馈等价的线性模型,再采用线性系统中成熟的极点配置的方法对虚拟的电机线性系统进行控制器的设计.该方法实现了转子位置和转子磁链的动态解耦,将多输入多输出强耦合非线性的永磁同步电机系统分解成了两个独立的单输入单输出的子系统.在此基础之上提出了带干扰随动的位置伺服控制器的设计方法,不但实现了位置的动态跟踪控制,而且还能对扰动进行动态跟踪补偿.仿真结果证实了其有效性和优越性.In this paper, a general method for multi-output tracking control of permanent magnet synchronous motor is presented. Nonlinear systems were firstly transformed to equivalent fictitious linear multi-input and multi-output systems （MIMO） by constructing diffeomorphism matrix. Therefore, controller can he designed by classic linear control theory. This method has realized dynamic decou- piing between the rotor position and the rotor flux linkage based on geometry theory. MIMO motor system has been divided into two simple-input and simple-output subsystems （SISO）. Then, position servo controller with disturbance rejection was provided based on the general method. Not only realized position dynamic precise tracking but dynamic compensation for disturbance, simulation and experimental results show its validity and superiority.
