Abstract: This paper investigates the problem of [L1] output tracking for network-based control systems with a single delay and parameter uncertainties. Attention is focused on the design of controller, which guarantees that the stability of systems and a prespecified L1 performance constraint level for the network-based control systems with respect to all peak-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 [L1] output tracking design scheme.

摘要： 将L1性能约束引入网络控制系统中，研究具有时延和不确定性的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峰值有界的外界扰动信号，网络控制系统具有L1性能约束水平。仿真实例证实了该设计方法的有效性。
