Abstract: In this paper, the concepts of structure for interval coefficients nonlinear interconnected control systems with multigroup time-delays are formulated. The structure and interconnected robust stabilization of interval variant coefficients interconnected control systems with multigroup time-delays and perturbation structure parameters is considered based on the equivalence method of robust stabilization given by Liu Yongqing. Meanwhile, the estimated formulas of bounds for delay and perturbed parameter of robust stabilization are given.
