Abstract:

Stability issue of uncertain systems is studied from a new viewpoint of reliability and based on quadratic σ stability criterion.A new method for robust stabilizing controller design of parametric uncertain systems that based on robust reliability consideration is proposed.The optimal robust controller design is carried out by an optimization based on reliability, and the controller designed by the presented method can satisfy the requirements for robust reliability in the sense of quadratic stability and the maximum robustness bounds of uncertain parameters can be provided.
