文摘For a class of value-bounded uncertain descriptor large-scale interconnected systems,the decentralized robust H∞descriptor output feedback control problem is investigated.A design method based on the bounded real lemma is developed for a decentralized descriptor dynamic output feedback controller,which is reduced to a feasibility problem for a nonlinear matrix inequality(NLMI).It is proposed to solve the NLMI iteratively by the idea of homotopy,where some of the variables are fixed alternately at each iteration to reduce the NLMI to a linear matrix inequality(LMI).A given example shows the efficiency of this method.
