确定稳定多项式的摄动界是系统鲁棒性研究的重要方法之一 ,通常使用代数方法来求解[1,2 ] 。对稳定多项式的摄动界给出了用根轨迹来确定的方法 ,避免了代数求解过程中复杂的约束条件 。
One of the important methods to study robustness of system is determination of the perturbation bounds of stable polynomials. It is solved usually by algebra. A new method to solve robust perturbation bounds of polynomials by means of root locations is presented in this paper, and the complex constrain conditions in the process of solution are avoided. Meanwhile the method presented in the paper is clear in concept, simple and powerful in practice. Finally, an example is given to show its efficiency.\;
