摘要
本文将一种新的模糊逻辑控制引入Buck变换器,模糊控制器通过双环反馈构成,外环是电压环,由模糊控制器构成,内环是电流环,由PI控制器组成。这种新的模糊控制方法,在传统的模糊控制的基础上,引入了电感电流作为反馈加以控制,能显著的改善系统性能。在Matlab的环境下,做了基于Buck变换器的双环模糊控制与传统模糊控制的仿真比较,结果证实了本文的可行性。
In this paper,a new fuzzy logic control mothod is introduced to the Buck converter,the fuzzy controller is composed by two loops. The outer is voltage loop,the inner is current loop. This new fuzzy control method is based on the conventional fuzzy controller,Introduced the inductance electric current as the feedback,it can remarkably improve the performance of the sistem. Then comparing it with the traditional fuzzy controller in Matlab simulation. The result confirmed the feasibility of this thesis.
