Consider a class of uncertainty models that are polynomial-function-dependent with perturbation parameters that reflect the physical meaning of the uncertainty information in the pre-determined part. The sufficient conditions and the maximum stable region estimation method for the robust stability of this kind of system with uncertainties are given. In the case of interval systems, this condition degenerates into an already-existing result, which indirectly indicates that the conditions in the text are conservative. The design method of the robust stabilization controller for state and output feedback is also given and the stabilization controller design algorithm with the maximum stability domain in the context of the method is presented. Finally, an example of robust stabilization controller design for flight control system is given, and the feasibility of the method in this paper is demonstrated.
