Abstract :
For the large-scale interconnected systems with value bounded uncertainties existing in the state, control and interconnected matrices, decentralized robust H2/Hinfin state feedback control problem was studied. Based on the bounded real lemma, the parametrization theorem for a decentralized robust H2/H infin state feedback controller was addressed and two LMI methods i.e. the direct LMI method and iterative LMI (ILMI) method were proposed to solve the problem. An example was given to show the application of two LMI method. The theory and simulation shows that the controller obtained has the block diagonal structure, ensures the closed-loop system asymptotically stable and offers an H2/H infin, perform index optimized
