针对含参数不确性、范数有界的Delta算子时滞系统,设计状态反馈控制器使闭环系统对所有允许的不确定性是鲁棒渐近稳定的,并且要求系统指定的输出指标满足给定的约束,此外还要寻找出系统的性能指标的最小上界.运用Lyapunov稳定性理论和线性矩阵不等式(LMI)方法,给出次优保性能状态反馈控制器存在的充分条件,进而提出最优保性能控制器的设计方法,最后通过数值算例验证该方法的可行性.
For a Delta operator with time-delay and bounded norm, a state feedback controller is designed to make the closed-loop system robust and asymptotically stable to all allowable uncertainties, and the output index of the system is required to satisfy Given the constraints, in addition to find out the minimum performance of system performance upper bound.Using Lyapunov stability theory and linear matrix inequality (LMI) method, the sufficient conditions for the existence of sub-optimal guaranteed state feedback controller, and then put forward The optimal guaranteed cost controller design method, and finally verify the feasibility of the method through numerical examples.
