  • Abstract: We introduce the funnel preâ€?compensator as a novel and simple adaptive preâ€?compensator of "highâ€?gain type". We show that this preâ€?compensator is feasible for a large class of signal pairs, which satisfy a certain relationship. We show that the funnel preâ€?compensator guarantees prescribed transient behavior of the compensator error, it is of low complexity and inherently robust since its design is modelâ€?free. As an application in adaptive control of nonlinear systems, a cascade of funnel preâ€?compensators is exploited to obtain an artificial output with explicitly known derivatives, which tracks the system output with prescribed transient behavior. In some important cases the interconnection of the system with the preâ€?compensator cascade is shown to have inputâ€?toâ€?state stable internal dynamics. This guarantees feasibility of a novel funnel controller that consists of a funnel preâ€?compensator cascade in conjunction with a recently developed funnel controller for systems with arbitrary relative degree. We illustrate the application of this interconnection for some mechanical systems.
