T-S modeling, Simulation and Control of the Buck Converter

According to the basic principle and the non-linear characteristic of the buck converter, this paper separately constructs the T-S fuzzy model of the buck electric circuit in two kinds of patterns which are CCM (continuous current mode) and DCM (discontinuous current mode). In order to get the circuit state equations and T-S fuzzy models in these two patterns, this paper introduces a switching function in DCM. The simulation results have indicated the T-S fuzzy modeling accuracy. Moreover, this paper puts forward another T-S model via the output error for the design of the fuzzy PDC (parallel distributed compensation) controller. Simulation results show that the fuzzy PDC controller has better dynamic characteristics than the PI controller.
