Abstract:

   For uncertain TS fuzzy systems with normbounded uncertainty and timedomain constraints, including control input constraints and state constraints, a robust optimal control scheme is proposed. The sufficient conditions for seeking state feedback gains are derived using SProcesure method. The design problem is then lead to solve an optimization problem with the constraints of a set of nonlinear matrix inequalities. An iterative algorithm for the solution of the problem is presented. Simulation is carried out for an inverted pendulum system and the results demonstrate the effectiveness of the proposed scheme.

Key words: automatic control technology, TSfuzzysystems, timedomainconstraints, uncertainties, obustoptimalcontrol, Srocesure
