摘要

本文旨在说明基于系统仿真技术的复杂方法的使用，以设计DC/DC转换器的模糊控制器。控制的目标是稳定开关调节器的电压输出，以对抗负载和反激拓扑的参数变化。该系统具有闭环结构不稳定的特点。对控制律的鲁棒性和高性能提出了更高的要求，特别是对大功率系统(200w以上)的控制律更是如此。为了获得良好的成本/性能比，规则和相关的成员函数必须通过模拟专用解决方案来实现，该解决方案能够获得更高数量的FIPS(每秒模糊推理)。

DC/DC converters fuzzy control

This paper aims to illustrate the use of a sophisticated methodology, based on system simulation techniques, to design a fuzzy controller for a DC/DC converter. The goal of the control is to stabilize the voltage output of the switching regulator against the load and parametric variations for a flyback topology. This system is characterized by being unstable in closed loop configuration. Robustness and high performances art requested to the control law especially for high power systems (more than 200 Watt). In order to obtain a good cost/performances ratio, the rules and the related membership functions have to be implemented via an analog dedicated solution capable to obtain an elevated number of FIPS (fuzzy inference per second).<>
