Robust H2/h∞ Dynamic Output-feedback Control Synthesis for Systems with Polytope-bounded Uncertainty
نویسندگان
چکیده
This paper presents a strategy for robust H2/H∞ dynamic outputfeedback control synthesis, with regional pole placement, applied to linear continuous-time time-invariant systems with polytope-bounded uncertainty. The proposed synthesis approach is based on a multiobjective optimization algorithm applied directly in the space of controller parameters. The H2 and H∞ norms, computed in all polytope vertices and in possible “worst case” interior points are taken as the optimization objectives. A branch-and-bound algorithm based on LMI guaranteed cost formulation is applied to validate the controller design. Examples are presented to show the effectiveness of the proposed strategy, including examples of full order and low order, centralized and decentralized control systems. Copyright c ©2005 IFAC.

Multiobjective Optimization Applied to Robust H2/H∞ State-feedback Control Synthesis
This paper presents an algorithm for robust H2/H∞ state-feedback control synthesis, with regional pole placement, based on a multiobjective optimization algorithm with non-smooth problem-solving capability. The problem is formulated with the state-feedback matrix coefficients as optimization parameters. The closed-loop performance obtained by means of the proposed strategy is assessed for the w...
متن کاملDevelopment of RMPC Algorithm for Compensation of Uncertain Time-Delay and Disturbance in NCS
In this paper, a synthesis method based on robust model predictive control is developed for compensation of uncertain time-delays in networked control systems with bounded disturbance. The proposed method uses linear matrix inequalities and uncertainty polytope to model uncertain time-delays and system disturbances. The continuous system with time-delay is discretized using uncertainty po...
متن کاملRobust H2 switching gain-scheduled controller design for switched uncertain LPV systems
In this article, a new approach is proposed to design robust switching gain-scheduled dynamic output feedback control for switched uncertain continuous-time linear parameter varying (LPV) systems. The proposed robust switching gain-scheduled controllers are robustly designed so that the stability and H2-gain performance of the switched closed-loop uncertain LPV system can be guaranteed even und...
متن کاملROBUST $H_{infty}$ CONTROL FOR T–S TIME-VARYING DELAY SYSTEMS WITH NORM BOUNDED UNCERTAINTY BASED ON LMI APPROACH
In this paper we consider the problem of delay-dependent robustH1 control for uncertain fuzzy systems with time-varying delay. The Takagi–Sugeno (T–S) fuzzy model is used to describe such systems. Time-delay isassumed to have lower and upper bounds. Based on the Lyapunov-Krasovskiifunctional method, a sufficient condition for the existence of a robust $H_{infty}$controller is obtained. The fuzz...
متن کاملRobust Mixed H2/H∞ Control of 2-Dimensional Systems in Roesser Model
The H2 performance specification for onedimensional systems has been known to be analytically and practically meaningful and widely used in the analysis and design of control and filtering systems. However, it is still of little use in the analysis and design of two-dimensional systems due to the structural and dynamical complexity of two-dimensional systems. In this paper, we extend the classi...
