多组时滞大型控制系统的镇定

^Stabilization of Large Scale Control Systems with Multi-group Time-delays

给出了由无时滞线性定常闭环孤立控制子系统的渐近稳定性推出多组时滞线性定常闭环大型控制系统的渐近稳定性的充分条件，并说明了所得结果可以推广到多组时滞线性时变闭环大型控制系统与多组时滞线性中立型定常（或时变）闭环大型控制系统．所得结果改进了前人的结果，通过参数镇定域的比较知，可使参数镇定域扩大为原来的６倍。

A sufficient condition is given, which ensures that the asymptotic stability of linear constant closed -loop isolated control subsystems without time-delays implies the asymptotic stability of linear constant closed-loop large scale control system with multi-group time-delays under certain conditions. And it is explained that the result can be extended to linear time-varying closed-loop large scale control system with multi-group time-delays and linear neutral type constant (or time-varying) closed-loop large scale. control system with multi-group time-delays, thus improving previous results. By the comparison of parameter stabilization region, the result is obtained that makes parameter stabilization region be expanded to 6 time of original one.
