Robust controller design for linear polytopic systems

Vojtech Veselý (2006)

Kybernetika

Similarity:

The paper addresses the problem of the robust output feedback controller design with a guaranteed cost and parameter dependent Lyapunov function for linear continuous time polytopic systems. Two design methods based on improved robust stability conditions are proposed. Numerical examples are given to illustrate the effectiveness of the proposed methods. The obtained results are compared with other three design procedures.

Robust and reliable H ∞ output feedback control for linear systems with parameter uncertainty and actuator failure

Chang-Jun Seo, Byung Kook Kim (1999)

Kybernetika

Similarity:

The robust and reliable H ∞ output feedback controller design problem is investigated for uncertain linear systems with actuator failures within a prespecified subset of actuators. The uncertainty considered here is time- varying norm-bounded parameter uncertainty in the state matrix. The output of a faulty actuator is assumed to be any arbitrary energy-bounded signal. An observer-based output feedback controller design is presented which stabilizes the plant and guarantees an H ∞ -norm bound...

Robust H ∞ control of an uncertain system via a stable decentralized output feedback controller

Ian R. Petersen (2009)

Kybernetika

Similarity:

This paper presents a procedure for constructing a stable decentralized output feedback controller for a class of uncertain systems in which the uncertainty is described by Integral Quadratic Constraints. The controller is constructed to solve a problem of robust H ∞ control. The proposed procedure involves solving a set of algebraic Riccati equations of the H ∞ control type which are dependent on a number of scaling parameters. By treating the off-diagonal elements of the controller transfer...
