摘　　要：从能量角度出发,将永磁同步电机看作是有能量输入和输出端口的装置.按照端口受控耗散哈密顿系统对其建模,利用互联和阻尼配置的能量配置方法,设计无源控制器.针对无源控制下的系统受到干扰时稳定性较弱,结合鲁棒控制技术,设计鲁棒无源控制器,以提高控制品质.系统转速调节采用滑模控制器,同时由负载转矩观测器估计实际转矩,增强系统抗负载扰动能力.仿真结果表明了该控制方法的有效性.The permanent magnet synchronous motor was considered as a device with energy input and output ports from the angle of energy.Modeling was done to PMSM based on the port-controlled Hamiltonian system with dissipation(PCHD)form,and the energy allocation method of interconnection and damping assignment was adopted to develop passivity-based controllers.In order to cope with the problem that the system under passivity-based control has weak stability when disturbed,robust passivity-based controllers were developed based on robust control technology to improve the control effect.The sliding mode controller was used to adjust the system speed,and at the same time,load torque observer was used to estimate the actual torque so as to enhance the system’s resistance to load disturbance.Simulation results prove the effectiveness of the control method.
