Abstract:  This paper gives a structural concept for linear interconnected control systems with multidelays，which is based on equivalence method of lyapunovʾs frequency area，a sufficient criteria is obtained for the interconnected stabilization of linear constant control system with mult-idelays，at the same time，the estimation of bound both time-delays and parametric perturbation are given．
