Design of Robust PI/PID Controller for Fuzzy Parametric Uncertain Systems

摘要: In this paper, a design method for robust PI/PID controller fuzzy parametric uncertain systems is proposed. An Linear Time Invariant (LTI) system with coefficients referred as system. The are approximated by intervals (crisp sets) using the nearest interval approximation approach to obtain an Further, designed necessary condition and sufficient stability of polynomial. These conditions used derive set inequalities in terms parameters which solved linear programming (LP) optimization controller. numerical examples simulation results successfully demonstrate efficacy proposed systems.
