【Abstract】 The system description with similarity is given, then robust decentralized stabilization for a class of nonlinear systems with sturcture uncertainties and similarity is discussed. A robust decentralized stabilizing controller is designed, which is composed of linear part and nonlinear part. It is shown that similar structure can simplify the analysis and design of composite systems. Moreover, the similar structures of nonlinear composite systems have the characters which can stabilize the systems.更多还原
