摘要:

本文研究了一类具有时延和凸多面体不确定性的随机网络控制系统的模型参考输出跟踪问题。基于线性矩阵不等式方法推出了该随机网络控制系统的稳定性和控制器设计的充分条件,并将控制器的设计转化为一个凸优化的求解问题。所设计的控制器能够保证相对于所有能量有界的外界扰动信号,随机网络控制系统的L2L∞性能指标小于一定值γ。仿真实例证实了该设计方法的有效性。

Abstract:

This paper studies the model reference output tracking problem for stochastic networkbased control systems with a single delay and parameter uncertainties residing in a polytope. Attention is focused on the design of controller, which guarantees that the stability of systems and a prespecified L2L∞ performance γ for the stochastic networkbased control systems with respect to all energybounded input signals. Sufficient conditions are proposed in terms of linear matrix inequality, and the corresponding controller design is cast into a convex optimization problem. A numerical example illustrates the effectiveness of the proposed L2L∞ output tracking design scheme.
