永磁同步电机的端口受控哈密顿控制

Research of vector control technology of PMSM based on port-controlled hamiltonian theory

在永磁同步电机的伺服控制系统中,绝大多数采用矢量控制和直接转矩控制,由于永磁同步电机是一种非线性的机电能量转换装置,运行时受电机参数的变化、负载扰动等因素对整个系统的稳定性、可控性影响较大。提出一种基于端口受控哈密顿方法建立了永磁同步电机的非线性数学模型,设计了一种端口受控哈密顿控制器,并分析了该控制器的鲁棒稳定性。对比传统PI矢量控制,通过仿真及实验结果表明所设计的端口受控哈密顿控制器具有优越的性能和较强的鲁棒性。

In servo system driven by permanent magnet synchronous motor（PMSM）, the majority control mode was vector control（VC） and direct torque control（DTC）. Since PMSM was a kind of nonlinear energy conversion devices that parametric variation and load disturbance have remarkable influence on dynamic stability and controllability of PMSM. A method based on the Port-controlled Hamiltonian was presented to establish the non-linear mathematical model of PMSM, to design the Port-controlled Hamiltonian controller, and to analyze the robustness of the controller.The simulation and experimental results show that the designed controller has well performance and strong robustness by compared with traditional PI vector controller.
