- Abstract
- In this paper the concept of multiple models and concept of switching controllers is used. The analog part of the system is described by finite set of discretetime models. It is considered general case when time-delay of real process is not equal to integer multiple of sampling time. As a set of controllers is used a finite set of LQ controllers with the prescribed degree of stability. The switching rule is based on the selection of the best performance of the closed-loop system. In the form of theorem is proved that hybrid system is asymptotically stable in the Lypunov sense and performance of system is no worse then the best non-switching strategy.
