Robust and non-fragile H-infinity reliable control for uncertain systems with ellipse disk pole constraints

In recent years, the multi object control has become a hot issue in field of engineering control, is used to find a solution that is able to meet various requirements. The paper studied the problem of how to design robust non-fragile reliable controller for a class of linear systems with norm bounded parameter uncertainty under the common constraints in elliptical disk pole constraint and interference suppression index. Against the controller gain changes with additive perturbations of case, robust non-fragile reliable controller is given based on linear matrix inequality. A numerical example is presented to illustrate the feasibility and effectiveness of the method.
