For a linear time-invariant structured perturbation, we have derived the sufficient conditions by the General Lyapunov Equation (G.L.E.) to check the system is stable or not. About those allowable stability bounds based on the Lyapunov criterion are extended to maximum bounds. Furthmore, the perturbation forms are more general than those have been considered in most of papers in past years. It is more practical to study the structure perturbed problem. Subsequently, we also proposed a new method to achieve the stable robustness, and we could know the exact suitable feed- back gain bounds and the exact gain values which make the system more stable. Besides, we could assign the parameters which we want to design by an optimal method. This algorithm is an efficient method to accomplish the each stop of design.
