Abstract

Based on the non-linear characteristic of BUCK-BOOST converter, combining with the fine part-linear characteristic of T-S fuzzy model, this paper constructs the T-S fuzzy model of the BUCK-BOOST converter under the kind of pattern which is DCM. Adopting PDC control scheme, it designs the BUCK-BOOST converterpsilas controller via CQLF method and obtains the controller parameters by using LMI method. Simulation results show that, T-S fuzzy model which based on BUCK-BOOST converter is reliable, and the fuzzy controller via T-S fuzzy model has better effects of stability and immunity to disturbance by comparing with PI control.
