【Abstract】 The problem of robust decentralized stabilization is considered for a class of uncertain time-varying large-scale uncertain system.The uncertainties are composed of two parts.One is the norm bounded manner,the other is the upper bounds of the uncertainties assumed to be unknown and not satisfying the matching conditions.Two classes of adaptive decentralized memoryless state feedback controllers are proposed.Based on Lyapunov stability theory,the sufficient conditions are obtained which can guarantee the state of the system asymptotical stability.A numerical example is presented which shows that the proposed methods are effective.更多还原
