Abstract :
Necessary and sufficient condition for robust H∞ control of dynamic interval systems is proposed. This robust H∞ controller guarantees not only the quadratic stability of the closed-loop systems but also the disturbance attenuation within a prescribed level in the H∞-norm sense. The results are obtained in terms of linear matrix inequalities. The illustrative example shows that this method is effective to obtain the robust H∞ controller for dynamic interval systems.
