摘要

有源调谐型混合电力滤波器的控制策略是滤波系统实现谐波抑制的关键技术之一。本研究结合有源调谐型混合电力滤波器的工作原理，指出了该滤波系统原有控制方法中采用PI调节控制器时存在的参数整定繁琐问题，进而在不影响系统滤波效果的前提下提出了一种可以克服该缺点的改进无差拍控制策略。本研究首先对该改进无差拍控制策略进行了理论分析，其次通过仿真与实验验证了该控制策略的可行性与正确性。%The control strategy for active tuned hybrid power filter is one of the key technologies for harmonic elimination.In combing with the operating principle of the power filter,this paper points out the problem of PI parameter adj ustment complexity of the existing control method. Furthermore,the deadbeat control strategy is proposed to overcome the drawback above men-tioned without affecting the filtering performance.In this paper,the theoretical analysis of the deadbeat control method is made and then the feasibility and correctness of the deadbeat control method is verified with the simulation and experimental results.
