On the internal model control of uncertain systems

Abstract

The robust control of an uncertain continuous linear system is evoked in this paper. The stability study for this class of system is based on the application of the Hurwitz and Kharitonov theorems. An approach of internal model controller synthesis for uncertain linear continuous systems is proposed in this paper. This approach is based on the use of a nominal model of the uncertain system. The case of an uncertain system is presented to show the effectiveness of this proposed control approach.
