中文摘要：

针对单独使用一种方法难以实现对永磁同步电机速度伺服系统快速、高效的控制问题，设计了基于反步法和最大输出功率原理的端口受控哈密顿协调控制方案。利用反步法解决系统的快速响应问题，应用最大输出功率原理使电机输出最大功率，采用指数函数作为协调函数来实现协调控制策略，从而适应永磁同步电机的负载扰动。仿真实验表明，该永磁同步电机速度控制系统的协调控制方案有效地结合了反步法和最大输出功率原理的端口受控哈密顿协调控制的优点，使系统的动态性能和稳态性能优良，且能够在负载扰动时快速消除误差。

英文摘要：

In view of the problem that the fast and high-efficiency control of permanent magnet synchronous motor(PMSM)speed servo system with one control method is difficult to realize,a hybrid coordination control scheme basedon backstepping and the port-controlled Hamiltonian(PCH)control on maximum output power principle was designed.The backstepping technique was used to optimize the dynamic response of the system,and the PCH control method wasapplied to ensure that the system reached its maximum output power.Furthermore,exponential function was utilized asthe coordination function to fulfill the coordination control strategy.The coordination control system was well adaptedto the load disturbance of PMSM.The simulation results show that the coordination control scheme which is applied toPMSM speed servo system combines the advantages of backstepping control and PCH control.The system has gooddynamic and steady-state performance,and it can eliminate the error quickly under the external disturbances.
