摘要
为进一步提高交流永磁同步电动机控制性能,本文提出了基于自适应逆控制的永磁同步电动机控制系统,采用基于递推最小二乘BP(RLS-BP)算法,对永磁同步电动机系统的进行建模、逆建模和自适应控制器的设计。提高了永磁同步电动机系统建模和逆建模的辨识收敛速度以及辨识精度和系统控制精度。仿真结果表明,基于本文提出的自适应逆控制方法的永磁同步电动机系统,具有良好的动态响应,并且在电机参数摄动情况下具有较强的鲁棒性。
This paper proposed an adaptive inverse control strategy for permanent magnet synchronous motor （PMSM）, in order to further improv the control performance of PMSM. The RI,S-BP algorithm was used to get PMSM system model, inverse model and controller. This algorithm improved the identification accuracy of model and inverse model. The control accuracy also improved by this method. The simulation results show that the performance of PMSM sys- tem based on the proposed adaptive inverse control has good dynamic performance and robustness when parameters change.
