A switching controller for the robust stabilization of uncertain interval MIMO plants using dynamic output feedback

Abstract

The robust stabilization problem for a family of linear uncertain interval MIMO plants is addressed, and a solution is presented based on switching control. The main feature of the paper is that the entire switching procedure is made using only information of the output variable. It has been shown that the proposed algorithm allows the shortening of the phase of 'scanning' among the different configurations with respect to existing algorithms, thus reducing the transient phase during which the system output may diverge because of destabilizing controllers applied. The present paper extends previous results to a wider class of plants.
