电力有源滤波器（Active power filter，APF）是消除电网中非线性负载产生的电流谐波的有效手段之一。提出一种三相静止坐标下的基于模型预测控制复合控制器，复合控制器由改进的自适应广义积分器和模型预测控制两部分组成。该复合控制策略有效地整合了预测控制和自适应广义积分器的优点，在最大限度利用模型预测进行谐波电流快速跟踪的同时，采取自适应广义积分器对各次谐波进行无静差跟踪控制。所提出的复合控制器与三电平电压空间矢量调相结合，能够消除单独预测控制交流变量时所存在的稳态误差问题和改善系统鲁棒性。详细研究了复合控制器的设计方法，并给出了系统的参数设计和稳定性分析。最后通过实验验证了控制方法的正确性和有效性。

Active power filter (APF) is one of the effective means to eliminate the grid harmonic current generated by nonlinear loads. This paper proposes a compound controller based on model predictive control under three-phase static coordinate. The compound controller consists two parts including improved adaptive generalized integrator and model predictive control. The composite control strategy effectively integrates advantages of adaptive generalized integrator and the model predictive control. Steady-state error is conducted by the adaptive generalized integrator under each harmonic current tracking control, at the same time model predictive control is used to track harmonic current at fastest speed. The proposed composite controller combined with three-level voltage space vector phase modulation can eliminate the steady-state error which exists only using the model predictive control strategy and improve system robustness. Detailed study of the composite controller design method is given, as well as the parameters of the system design and stability analysis. Effectiveness and correchness of the control method proposed are finally verified by experiments.
