The robust stabilization of large scale systems with parameter perturbation

Since systems are generally often subject to some forms of perturbation, such as unmodelled dynamics, environmental variations, and parameter uncertainties, the robust stability is one of the most important things to be considered. Owing to its complexity and largeness, the large scale system is more easy to suffer uncertainties than the small one. Thus in this paper, we consider the robust stability of large scale system with parametric perturbation. The sufficient condition of the robust stability is derived via comparison theorem and norm theory from the viewpoint of time domain. Also, a design procedure is proposed to find a controller to satisfy the robust stability condition.
