摘要

本文提出了一种模糊与PI的混合控制方法,以解决Buck变换器输出电压的稳定性问题,特别是在小功率应用中。本文的主要贡献有两点。首先是在Matlab中设计了一个简单的模糊pi输出电压控制buck变换器的设计。第二部分是对传统PI控制系统与所设计的模糊-PI混合控制系统的响应进行了比较。所采用的方法是三阶段模拟。该过程从Fuzzy-PI控制器的设计,3个场景的仿真测试,以及比较验证,即PI控制器开始。仿真的目的是观察系统对输入电压、参考电压和负载电阻变化的响应。根据测试结果可知,在每次参数变化时,模糊PI控制比PI控制更能保持降压变换器输出电压的稳定性。

Fuzzy-PI Control for Buck Converter Output Voltage Stabilizer
This paper presents a hybrid control between Fuzzy and PI to solve the problem of stability of the output voltage on the Buck Converter, especially in small power applications. This paper makes two main contributions. The first is the design of a simple Fuzzy-PI output voltage control design of a buck converter in Matlab. The second is the result of comparing the response of the traditional PI control system with the designed Fuzzy-PI hybrid control. The method used is a simulation with 3 stages. This process starts from the design of the Fuzzy-PI controller, simulation test with 3 scenarios, and verification with a comparison, namely the PI controller. The purpose of the simulation is to see the response of the system to changes in input voltage, reference voltage, and load resistance. Based on the test results, it is known that the Fuzzy-PI control is better than the PI control in maintaining the stability of the buck converter output voltage at every parameter change.
