摘要
针对传统永磁同步电机电流预测控制易受电机内部参数摄动影响的问题,研究一种考虑电机内部参数摄动的自适应鲁棒电流预测控制算法。基于Lyapunov稳定性判据,设计自适应扰动观测器在线观测d,q轴系统扰动,用以实时补偿电流预测控制器的输出电压,校正系统扰动引起的模型失配,提高电流预测控制的抗参数摄动性能。实验给定永磁同步电机定子电阻、电感以及转子磁链三种参数摄动情况,结果验证了该自适应鲁棒电流预测控制算法的优良性能。
Since conventional permanent magnet synchronous motor current prediction control is susceptible to perturbation of internal parameters,an adaptive robust current prediction control algorithm considering the perturbation of internal parameters was studied.Based on Lyapunov stability criterion,adaptive perturbation observer was designed to observe the dq axis system perturbation online,and it was used to compensate the output voltage of current prediction controller promptly and correct the system mismatch caused by system disturbance.The anti-parameter perturbation performance of current prediction control was improved.Three parameters perturbation of motor stator resistance,inductance and rotor flux were given in the experiment,and the results verify the excellent robust performance of the proposed current prediction control algorithm.
