Based on Adaptive Fuzzy PI Control APFC Research

随着电力电子技术的发展,电力电子设备在工业、农业等领域都得到了广泛的应用。这些设备中的非线性器件产生的谐波污染问题给工业生产和社会生活带来了危害与不便。因此,提高功率因数消除谐波成为电力电子技术一个重要的研究方向。本文重点介绍了模糊自适应控制器和常规PI控制器组成的模糊自适应PI控制器的设计方法,并用这种方法设计了一个有源功率因数校正(APFC)系统。通过MATLAB仿真表明,引入模糊PI控制设计的APFC系统具有响应快,稳态精度高,功率因数提高显著的优点。

Along with the power electronic technology development,the power electronic equipment in industry,agriculture and other fields have been widely used.The non-linear device in these devices generate harmonics pollution problems to the industrial production and social life of the hazards and inconvenience.Therefore,improving the power factor of power electronics technology to eliminate harmonics become an important research direction.This paper introduces the adaptive fuzzy controller and PI controller of adaptive fuzzy PI controller design method,and the method to design an active power factor correction（APFC） system.Through the MAT-LAB simulation shows that Introduction of fuzzy PI control design of the APFC system with quick response and steady-state,high precision,power factor raise significant advantages.
