Abstract

This paper presents a new positive output voltage buck-boost converter is introduced, so that voltage gain is squared the times of conventional buck-boost converter with positive voltage polarities, these advantages enable to work in wide range of applications. It is essential to stabilize the output voltage of DC to DC (Chopper) converter, a suitable controller is necessary for that design and implementation of linear PI controller and Nonlinear Fuzzy controllers are employed. The steady-state as well as transient analysis have been done for both the PI and Fuzzy control techniques with the help of MATLAB/Simulink platform. A comparison analysis is made between both the methods in terms of their performance. In ordered to check the feasibility of the converter and PI controller, the small-scale experimental setup has been fabricated in the laboratory environment and validation has been done by experimental results for the buck-boost converter along with closed loop PI control strategy.

一种新型Buck-Boost变换器PI与模糊控制策略的比较研究

本文介绍了一种新的输出电压为正的buck-boost变换器，它的电压增益是传统电压极性为正的buck-boost变换器的平方倍，具有广泛的应用范围。稳定DC - DC(斩波)变换器的输出电压是至关重要的，在设计和实现线性PI控制器和非线性模糊控制器时，需要一个合适的控制器。利用MATLAB/Simulink平台对PI控制和模糊控制技术进行了稳态和暂态分析。对两种方法的性能进行了比较分析。为了验证变换器和PI控制器的可行性，在实验室环境下制作了小型实验装置，并通过实验结果对buck-boost变换器和闭环PI控制策略进行了验证。
