摘要
针对一类时延网络控制系统,研究了当存在有限能量外部扰动时,系统的最优状态反馈非脆弱H_∞控制律的设计问题。通过将时延看作系统的时变参数不确定性,应用H_∞鲁棒控制理论及线性矩阵不等式(LMI)技巧,给出了具有控制增益扰动的次优非脆弱H_∞控制律存在的充分条件,提出了最优非脆弱H_∞控制律的设计方法。数值仿真例子表明了所提方法的有效性。
The problem of optimal non-fragile H∞ control via state feedback is investigated for a class of networked control systems with network-induced delays and limited external disturbance. By viewing the timevarying delays as time-varying parameter uncertainties, sufficient condition for the existence of suboptimal nonfragile H∞ control with control gain perturbation is developed by applying H∞ control theory and linear matrix inequality （LMI） technique. The design method for optimal non-fragile H∞ control law is presented. Finally, simulation result illustrates the effectiveness of the proposed approach.
