Abstract :
The problem of the robust stability and non-fragile control of closed-loop system is studied for the system with structured uncertainties both in plant and controller. Non-fragile robust stability and performance sensitivity of the closed-loop system with left coprime factor perturbations and right coprime factor perturbations are investigated respectively, and the sufficient conditions are given for the non-fragile robust stability of perturbed system under the certain conditions as well. At last the relation of non-fragile robust stability between the two aspects is given.
