摘要
针对永磁同步直线电机(LPMSM)速度控制问题,从能量成型的观点出发,将其看作能量转换装置,采用端口受控耗散哈密顿(PCHD)理论推导出LPMSM系统的端口受控哈密顿模型.在哈密顿结构基础上利用互联和阻尼配置,给出闭环系统期望的哈密顿函数,对速度控制器进行了设计.设计中直接采用哈密顿函数作为存贮函数,使系统在满足无源性的条件下达到了要求的性能,具有明确的物理意义.仿真结果表明,设计的闭环控制系统能够快速响应负载阻力的变化,具有良好的鲁棒性.
In view of the speed control problem of the linear permanent magnet synchronous motor （LPMSM） , which is viewed as an energy-transformation device, from the viewpoint of energy shaping, applying port-con- trolled Hamiltonian with dissipation and passivity-based control theory, the port-controlled Hamihonian model of LPMSM is deduced. Based on the Hamiltonian structure, the desired Hamiltonian function of the closed- loop system is given, and the speed controller is designed by using the method of intereonnection and damping assignment. In the design, the Hamiltonian function is used directly as the storage function, and the system can achieve the required performance and bring more definite physical meaning on the condition of satisfying passivity. The simulation results show that the closed-loop control system can respond quickly to changes in load resistance and has good robustness.
