Stability of unfalsified adaptive control with non-SCLI controllers and related performance under different prior knowledge

The paper addresses two aspects related to adaptive switching supervisory control. The first pertains to the study of cost-detectable cost functions whose minimization guarantees internal adaptive stability of the controlled system, whenever stabilization is feasible. In this context, a new class of cost functions which removes the SCLI controller requirement in order to have cost-detectability is presented. The second aspect is the analysis of switching performance achieved using such cost functions. Both aspects are considered in the case where no a priori knowledge on the plant is available as well when nominal approximating models of the plant are known.
