基于自适应反步法和端口受控哈密顿理论的永磁同步电机控制∗

摘要

提出了一种基于自适应反步控制和端口受控哈密顿( PCH)系统理论的永磁同步电机( PMSM)速度控制方法。考虑电机负载扰动，提出了基于反步法的PMSM速度环自适应控制；然后将PMSM电磁子系统模型表示成哈密顿系统形式，根据PCH系统理论求得控制器。仿真结果表明，设计的控制方法能够快速达到期望的转速值，且具有较好的抗负载扰动能力。%The speed control method of permanent magnet synchronous motor ( PMSM ) based on adaptive backstepping and port-controlled hamiltonian theory( PCH) was propsed. First, considering the load disturbance of the motor, adaptive control of speed loop for PMSM based on backstepping method was proposed; then the electromagnetic subsystem model was expressed as a Hamiltonian form, for which the controller was obtained according to the PCH theory. The simulation results showed that the method could quickly reach the expected value of speed,and had good resistance to the load disturbance.
