AC/DC Converter AC Side Harmonic Wave Detection Based on Self-adaption Fuzzy PID Controlling

Li Jia-Sheng

Abstract:
As AC/DC converter is a non-linear and time varying uncertain system, it is hard to reach the ideal control effect if adopting the routine Proportional Integral Differential (PID) control which is bad in dynamic property. A compound control scheme is proposed in this study which combines PID control and fuzzy self adaption. It takes error e and error variation ec as input and modifies PID parameter by using fuzzy control rule on line to satisfy the requirements of e and ec on PID parameter self tuning in different times. The experiment simulation indicates that the proposed scheme can minimize the AC side distortion factor and get better sine wave. Additionally, this scheme is simple, effective and practical in certain degree.
