Abstract:: Robust control problems of MIMO linear systems with both plant and controller subject to additive norm-bounded perturbations are studied, and LMI-based controller design method is given. The relation between the conditions of robust analysis and robust synthesis is also given. In addition, robust performance problem is considered again, a better sufficient condition is presented.
Key words:: LMI; Norm-bounded; Robust performance
