【Abstract】 Due to the error of system modelling and the change of working environment,the uncertainty of the system is inevitable.This paper presents an improved analysis method for networked control systems with time-varying structural parameter uncertainry.By setting the logic Zero-order holder(ZOH)which makes the packet out-of-order and data dropout is dealed with.We employ the free weighting matrices to deal with cross product items in our derivation to obtain the sufficient condition of the closed-loop system asymptotically stable.Finally,the simulation example shows the effectiveness and feasibility of the presented method.更多还原
