Abstract

The paper addresses the control problem of complex plants, using state space realizations derived from Takagi-Sugeno fuzzy models. In particular, a state feedback controller, based on the estimated state information, is proposed for the regulation of gas furnaces. The method described comprises procedures to design a converging state estimator and a stabilizing controller respectively. It is shown that if the estimator and controller gains satisfy an additional sufficient condition then the observer-based closed loop is stable. Simulation studies on the fuzzy model of the gas furnace process verify the result
