| 摘 要： | 对不同类型的模糊PID控制器(模糊P控制器、模糊PD控制器、模糊PI控制器、模糊PID控制器)在DC/DC变换器中的应用作了全面的研究。目前,模糊PI控制器应用得最为广泛,然而在其控制作用下,DC/DC变换器的输出电压通常会超调,并且当响应时间较短时有很大的冲击电流尖峰。探讨一种变结构模糊控制器,这种控制器将有效地克服模糊PI控制器的上述不足。基于Matlab/Simulink对应用变结构模糊控制器控制的DC/DC变换器系统进行了计算机仿真。仿真结果表明,变结构模糊控制器控制拥有较好的动态特性和稳态性能。

| Abstract: | This paper presents a comprehensive study of different types of Fuzzy-PID controllers, such as Fuzzy-P, Fuzzy-PD, Fuzzy-PI, and Fuzzy PID, for DC-DC converter.Fuzzy-PI Controllers are the most popular.However ,they generally give overshoot in output voltage and high initial current especially 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 investig... |
