摘要
为了改善永磁同步电动机系统的动态性能,解决传统反步法的“计算复杂性”问题,提出了永磁同步电动机的事件触发指令滤波离散控制方法。采用指令滤波控制技术处理传统反步法中的“计算复杂性”问题,利用补偿信号消除了滤波误差,提高了系统的控制精度;运用自适应模糊控制方法处理模型中的未知非线性函数;通过设定事件触发条件来判断系统的自适应律和控制律是否需要更新,减轻了计算负担,节省了计算资源。仿真结果验证了文中所提控制方法的有效性。
In order to improve the dynamic performance of permanent magnet synchronous motor(PMSM)system and solve the “complexity of computation” problem of the traditional backstepping method, an eventtriggered command filtered discrete-time control method is proposed for PMSMs. The command filtered control technology is used to deal with the “complexity of computation” problem of the traditional backstepping method,and the compensation signal is introduced to eliminate the filtering error and improve the control accuracy of the system. The adaptive fuzzy control method is used to deal with unknown nonlinear function in the model. By setting the trigger conditions of event-triggered control, it is judged whether the adaptive law and control law of the system need to be updated, which reduces the computational burden and saves computational resources. The simulation results show the effectiveness of the proposed control method.
