The issue of non-fragile decentralized control is addressed under state feedback controller gain perturbation for singular large-scale systems.Sufficient conditions for the existence of the non-fragile decentralized controller are obtained under the two classes of gain perturbations,namely,additive and multiplicative by linear matrix inequality(LMI) approach,respectively.They are a set of linear matrix inequalities(LMIs).With the feasible answers of these inequalities,the non-fragile decentralized controller designs for singular large-scale system under the two classes of gain perturbations are given.The designed controllers are such that the closed-loop systems are regular,stable and impulse free.Finally,an illustrative example is given to show the feasibility and effectiveness of the design.
