摘要

摘要: 讨论具有参数区间不确定性的线性周期离散时间系统的反馈控制问题．首先进行系统的鲁棒稳定性分析和镇定研究，分别给出了基于线性矩阵不等式的系统渐近稳定和状态反馈镇定的条件．接着研究系统的L2-增益分析和控制综合问题．对于L2-增益分析问题，得到一个基于线性矩阵不等式的条件，在该条件下，具有参数不确定性的线性周期自治系统渐近稳定，且有小于γ的L2-增益．对于控制综合问题，导出基于线性不等式的条件，由该条件可以得到一个状态反馈器，使得闭环系统渐近稳定，且有小于γ的L2-增益．所有这些条件都是充分必要的．

Abstract: Feedback control problems for linear periodic systems (LPSs) with interva-l type parameter uncertainties are studied in the discrete-time domain.First,the stability analysis and stabilization problems were addressed.Conditions based on linear matrices inequality for asymptotical stability and state feedback stabilization respectively were given.Problems of B2-gain analysis and control synthesis problems were studied.For the B2-gain analysis problem,an LMI-based condition was obtained such that the autonomous uncertain LPS is asymptotically stable and has an B2-gain smaller than a positive scalar gamma.For the control synthesis problem,an LM-Ibased condition was derived to build a state feedback controller ensuring the closed-loop system is asymptotically stable and has an B2-gain smaller than a positive scalar gamma.All the conditions are necessary and sufficient.
