本文讨论了带有结构性不确定的线性时变系统的二次镇定问题.建立了H∞指标γ和RDE及RDI之间的等价关系，并给出了带有结构性不确定线性时变系统二次稳定的充分条件;在此基础上将带有结构性不确定线性时变系统的鲁棒动态补偿器设计转化成求解一个相应的确定性辅助线性时变系统的

In this paper, the quadratic stabilization of linear time-varying system with structural model uncertainty is discussed. First, an equivalence relation between H∞ index γ, RDE and RDI is established. Second, the sufficienct condition for a lin
