摘要

本文设计了一种用于开关电流型DC/DC升压变换器的模糊控制器。所提出的简单模糊逻辑控制器具有9条规则，通过减小电流频谱峰来提供最优斜率补偿，使系统充分远离第一个分岔点。尽管变换器具有非线性和不稳定性，但由于避免了分岔现象，闭环控制系统的性能得到了很大的提高。结果表明，在运行工况变化情况下，所采用的调节和跟踪方式均能取得满意的效果

Control of Bifurcation by Fuzzy Logic Controller for Current-mode Boost Converters

This paper presents the design of a fuzzy logic controller for switching current-mode DC/DC boost converters. The proposed simple fuzzy logic controller, with nine rules, provides an optimal slope compensation to keep the system adequately remote from the first bifurcation point by means of reducing the current spectrum peak. In spite of nonlinear characteristics and instabilities of the converter, the performance of the closed-loop control system can be considerably improved to avoid bifurcation phenomena. It is found that the technique introduced in this paper gives satisfactory results with the regulating and tracking modes under changes in operating conditions
