Parameter Adjustment Rules and Algorithm of Fuzzy Self-adaptive PID Controlling on Sepic Converter

模糊自适应PID控制已经在各类电力电子装置中得到普遍应用,可以实现对PID参数的最佳调整。目前该控制方法已应用于Buck和Boost直流变换器上,在理论和实践应用上都取得良好效果。本文以Sepic变换器为研究对象,将模糊自适应PID控制方法应用于此型变换器上,通过对整定规则的理论分析和仿真研究,进而得出了模糊自适应PID控制方法的仿真效果。

The fuzzy self-adaptive PID controlling method has been widely used in all kinds of power electronic devices, which can realize the best PID parameters adjustment. Now this method has been used in Buck and Boost DC converters, whose academic and practical applications are both satisfying. In this paper, fuzzy self-adaptive PID controlling is used on Sepic DC converter, correspondant analysis and simulation are done to testify the applicability on both of the controlling method and Sepic converter.
