Fuzzy bilinear state feedback control design based on TS fuzzy bilinear model for DCDC converters
This paper proposes a fuzzy bilinear state feedback controller based on TagakiSugeno (TS) fuzzy bilinear model for DCDC converters. The DCDC converters can be approximated to bilinear model via Taylor series expansion. For achieving the output voltage regulation, we formulate the extended system of bilinear DCDC converter model, one of whose state variables is the error between the output voltage and the reference output voltage. The extended system can be described to TS fuzzy bilinear model. We design a fuzzy bilinear state feedback controller to track the reference output voltage. The closed loop system is globally asymptotically stable via the proposed controller. Lyapunov theory is employed to guarantee the stability of the closed loop system. Numerical examples are given to demonstrate the validity of our proposed control approach with comparative results.
