Analysis and Control of a Class of Uncertain Linear Periodic Discrete-Time Systems

  • 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.
