摘　　要：针对电动汽车用永磁同步电机驱动系统在实际工况中存在的负载扰动问题,提出了一种基于Hamilton系统H∞控制理论的扰动抑制算法。首先在已有的考虑铁损的永磁同步电机的Hamilton实现及镇定控制的基础上,设计了永磁同步电机的Hamilton H∞控制器;然后分析了负载扰动情况下,采用Hamilton H∞控制前后以及不同干扰抑制水平下,各电流分量、转速和电磁转矩的响应情况。仿真结果表明:Hamilton H∞控制具有很好的负载扰动抑制能力,有助于提高电动汽车的驾乘舒适性。Aimed at inhibiting the load disturbance in permanent magnet synchronous motor （PMSM） under the actual working condition of electric vehicles, a new type of disturbance inhibition method was presented based on Hamiltonian system H∞ control theory. On one hand, a Hamiltonian H∞ controller was designed on the basis of Hamiltonian realization and stabilizing control of PMSM considering iron loss. On the other hand, the response of currents, rotating speed and electromagnetic torque were analyzed under different disturbance inhibition level when the load disturbance existed. The simulation results show that the proposed Hamiltonian H∞control has strong anti-disturbance ability which is useful to the drivability and comfort of the electric vehicle.
