摘要
This paper presents a robust observer-based H-infinity controller design method via LMIs for a class of switched discrete-time linear systems with l(2)-bounded disturbances and parameter uncertainties. The main contribution of this paper consists in a new and judicious use of the slack variables coming from Finsler's lemma. We show analytically how the proposed slack variables allow to eliminate some bilinear matrix coupling. The effectiveness of the proposed design methodology is shown through a numerical example.
