PERFORMANCE AND SYNTHESIS FOR SYSTEMS WITH H-DISSIPATIVE UNCERTAINTY

摘要

New control synthesis algorithms are proposed for robust disk pole assignment and H{sub}2 guaranteed cost with H-dissipative uncertainty models. The H-dissipative uncertainty modelling has proved to be a new promising way to consider state-spaceuncertain model. The results of this paper are based upon quadratic d-stabilisability and only dynamic output feedback is considered. It is shown that the problem can be recast as a non-convex optimisation problem, (minimisation of a quasi-concavefunction over a convex set) for which a numerical algorithm is used to solve it.
