Abstract

Inherent time-varying and heavy nonlinearity make the power electronic converter have many difficulties in control. Classical control approach can not reach ideal control effect. A kind of sliding mode double-loop control method is designed in this paper. To overcome the chattering caused by sliding mode control and improve the system stability further, fuzzy logic is introduced to improve the sliding control scheme. Simulation results show that this approach has good control result, and it has good robustness to changes in input and load.
