摘要
把永磁同步电动机(PMSM)看作一个二端口的能量交换装置,基于能量成形方法和反馈耗散哈密顿理论,实现了永磁同步电机的速度控制.根据最大转矩/电流控制原理确定系统的期望平衡点,针对负载转矩已知和未知2种情况分别设计了速度反馈控制器,并分析了系统的稳定性.仿真和实验结果表明,所设计的控制器具有良好的鲁棒性和快速响应性,是有效的.
A novel method based on the theory of Hamihonian systems for speed control of permanent magnet synchronous motor (PMSM) was presented. PMSM can be viewed as a two-port energy transformation device. Based on energy-shaping method and feedback dissipative Hamihonian realization (FDHR), the speed controller of P.MSM was given. The system' s desired equilibrium was obtained according to maximum torque per ampere ( MTPA) control rule, then the feedback law was constructed respectively in torque known and unknown cases, where each system' s stability was also verified. The simulation and experiment results show that the proposed scheme has a good robustness and fast response, thus the controllers designed in this way are efficient.
