Study on Fuzzy Adaptive Logic Controller Used in DC/DC Converter

提出了一种应用于DC/DC变换器的模糊自适应PI控制器。在传统PI控制的基础上,设计了对PI参数进行在线调节的模糊自适应控制算法。对该算法建立了基于Matlab的仿真模型,并通过ARM控制器对其进行软硬件实现。以Buck电路为被控对象的计算机仿真和实验结果表明,模糊自适应PI控制简单可靠,实现了快速性与稳定性的统一。

This paper presents a fuzzy adaptive logic PI controller for DC/DC converter. On the basis of traditional PI controller, fuzzy adaptive logic controller is designed to adjust real time PI parameter. For the algorithm simulation model is established based on Matlab and the hardware and software is set up through ARM controller. The results of simulation and experiment for Buck converter prove that the fuzzy adaptive logic control is simple and reliable. The control scheme can achieve more stable and more dynamic performance .
