| 摘 要： | 针对永磁同步电机磁链变化时会对电机运行产生影响的问题,依据哈密顿反馈耗散理论,在磁场同步旋转坐标系下,选择定子电流和转子转速为系统状态变量,研究转子永磁体磁链变化时对电机转速的影响,并给出了基于哈密顿反馈耗散理论的磁链自适应估算方法.仿真结果表明:该方法能够准确地跟踪永磁体转子磁链变化的真实情况,对电机参数不敏感,鲁棒性强,在磁链发生改变的情况下控制器能够快速估算磁链的改变值,使电机转速实现快速稳定,达到了控制精确度要求.

| Abstract: | Aiming at the negative influence of motor speed regulation caused by rotor flux uncertainty,based on Hamilton feedback dissipative control(HFDC) theory,stator current and motor speed in magnetic field synchronously rotation coordinate were chosen as system state variables,and the influence of motor's speed was studied when rotor's flux was changed,then the flux adaptive estimate method based on Hamilton feedback dissipative control theory was brought out.The simulation result shows this method can accuratel... |
