摘要
有源滤波器控制的目标是使逆变器的输出迅速、准确地跟随参考信号的变化,要求控制器实时性强、复杂度小、精度高,具有良好的自适应性和鲁棒性。该文结合单独注入式有源电力滤波器的结构特点,在已有数学模型的基础上,提出了基于分频的自适应控制新方法,并分析了相应的控制性能,仿真结果证实了所提方法的可行性和正确性,对滤波器的设计和使用具有一定的理论指导意义和实用价值。
The control objectives of the active power filter consist of causing output of the to follow the change of the reference signal rapidly and accurately, Strong timeliness, small complexity, high precision, good adaptation and robustness. According to the construction feature of active power filter with single injection and its mathematical model, an adaptive control based on the separate frequency is proposed, and the corresponding control scheme is analyzed. Simulation results verify the feasibility and accuracy of the proposed method. It provides some practical and theoretical values to the design and use of active power filter.
