Abstract

Hysteresis switching adaptive control systems designed using certain types of 𝔏~2𝔒~‐gain‐type cost functions are shown to be robustly stabilizing if and only if certain plant‐independent conditions are satisfied by the candidate controllers. These properties ensure closed‐loop stability for the switched multicontroller adaptive control (MCAC) system whenever stabilization is feasible. The result is a safe adaptive control system, which has the property that closing the adaptive loop can never induce instability provided only that at least one of the candidate controllers is capable of stabilizing the plant.

The notion of input-to-state stability (ISS) has proved to be useful in nonlinear systems analysis. This paper discusses a dual notion, output-to-state stability (OSS). A characterization is provided in terms of a dissipation inequality involving storage (Lyapunov) functions. Combining ISS and OSS t
