摘要

本文综合研究了不同类型的类PID模糊控制器，如fuzzy- p、fuzzy- pd、fuzzy- pi和fuzzy PID，用于DC-DC变换器。Fuzzy-PI控制器很流行。然而，当响应上升时间减少时，这些通常会导致输出电压超调和高初始电流。针对模糊pi控制器的这些缺点，本文提出了一种变结构模糊控制器(VS-FLC)。计算机仿真研究了该变结构FLC控制器应用于DC-DC变换器系统的性能，获得了较好的启动和稳态性能。

Application of variable structure fuzzy logic controller for DC-DC converters

This paper presents a comprehensive study of different types of PID-like fuzzy logic controllers, such as fuzzy-P, fuzzy-PD, fuzzy-PI, and fuzzy PID, for application to DC-DC converters. Fuzzy-PI controllers are popular. However these generally give overshoot in output voltage and high initial current when rise time of response is reduced. A variable structure fuzzy logic controller (VS-FLC) is proposed in this paper to overcome these disadvantages of fuzzy-PI controllers. Computer simulations are performed to investigate the performance of the proposed variable structure FLC controller applied to a DC-DC converter system and better starting and steady state performance is obtained.
