摘　　要：采用能量成形和互联、阻尼配置的无源性控制方法,完成了永磁同步电机的端口受控哈密顿系统(PCH)的建模。在此基础上提出了一种新的永磁同步电机的PCH双闭环调速系统。外环速度调节由滑模速度控制器实现期望的q轴电流,内环电流调节由无源控制器实现d-q旋转坐标系下的两个电压分量ud和uq。针对系统转速估计问题,利用一种基于自适应速度估计的滑模观测器观测速度,节约了成本和增强了系统的可靠性。仿真结果表明了该方法的有效性,控制系统具有良好的动静态性能。Based on the energy-shaping and the interconnection and damping assignment passivity-based control method,the model of the port-controlled Hamiltonian（PCH） control system for the surface permanent magnet synchronous motor（SPMSM） was designed.On this basis,a new double loop speed control PCH system was proposed for PMSM.The outer loop control was employed by sliding mode controller to determine anticipant q axis current.In the ineer loop,passivity-based control was designed to produce the ud and uq.A novel speed sensorless method was put forward by using a sliding mode control based adaptive speed estimator,which could reduced cost and system＇s reliability was enhanced.The simulation results show that the method is effective and the system has a satisfactory performance.
