Robust H∞ Output Feedback Control Design for Uncertain Fuzzy Systems with D Stability Constraints: an Lmi Approach

Abstract: This paper addresses the problem of designing a robust output feedback controller for a class of fuzzy uncertain dynamic systems that guarantees i) the L2gain from an exogenous input to a regulated output is less or equal to a prescribed value and ii) the closed-loop fuzzy system to be quadratically stable within a prespecified LMI stability region. Based on an LMI approach, solutions...

Robust H , Output Feedback Control for Nonlinear Systems Matthew

In this paper we present a new approach to the solution of the output feedback robust H , control problem. We employ the recently developed concept of information state for output feedback dynamic games and obtain necessary and sufficient conditions for the solution to the robust control problem expressed in terms of the information state. The resulting controller is an information state feedba...

Parametrization and Convex Approximation Approach to Stabilization via Output Feedback

A parametric description of all static output feedback stabililizing controllers for switching diffusion systems is presented. This description is expressed in terms of coupled linear matrix equations and non-convex quadratic matrix inequalities which depend on parameter matrices similar to weight matrices in LQR theory. A convexifying approximation technique is proposed to obtain the LMIbased....

Robust Hinf Load-Frequency Control for Interconnected Power Systems with D-Stability Constraints Via LMI Approach

The aim of this paper is to investigate the problem of robust H∞ load-frequency control for interconnected power systems with circular pole constraints. The problem we address is to design both state feedback and output feedback controllers such that, for all admissible parameter uncertainties, the closed-loop system satisfies not only the prespecified H∞ norm constraint on the transfer functio...
