摘要
针对有源电力滤波器(APF)系统自身同有延时造成APF补偿性能下降问题,提出了一种基于广义预测控制(GPC)策略。根据GPC理论,设计了三相四线制APF预测控制结构模型,建立了APF的受控自回归积分滑动模型。在此基础上讨论GPC预测控制器的设计方法,实现了对三相四线制APF电流的预测控制。设计了最优控制规律。仿真试验结果表明,广义预测控制具有较好的跟踪能力,克服了系统延时造成的网侧电流存有毛刺的现象。
Focusing on the problem of the reduction that active power filter（APF） compensating ability caused by the system inherit time propagation delay of APF, this paper gave a control strategy based on generalized predictive control（GPC）. The GPC model and the CARIMA model of three-phase four-wire APF were designed on which the predietable current control of the three-phase four-wire APF was achieved. The optimized control rules were designed. The simulation results prove that the GPC strategy has the benefit of good tracing capacity and eliminates the current glitch on the network side.
