A switching controller for the output feedback stabilization of uncertain interval plants via sliding modes

Abstract

The robust stabilization problem for a family of linear uncertain interval plants is addressed, and a solution is presented based on switching control. The main feature of this note 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.
