Robust adaptive stabilization of a class of systems under structured nonlinear perturbations with application to interconnected systems

This paper presents a stabilization scheme for a class of multi-input/multi-output systems with nonlinear additive perturbations using high-gain adaptive controllers. The nominal system is assumed to satisfy some mild conditions required by standard adaptive control schemes, and the perturbations certain structural conditions. The controller is a dynamic output feedback containing a gain parameter, which is adjusted with a simple adaptation rule. The result is also applied to decentralized stabilization of a class of interconnected systems, where the interconnections are treated as perturbations to nominally decoupled subsystems.

Simulation of a high-gain adaptive speed-regulating system for an internal combustion engine

An analog computer has been used to simulate a high-gain adaptive control method for regulating the speed of an internal combustion engine. A nonlinear element (an on-off relay) main tains the high gain in the forward loop that is necessary to produce a one-to-one relationship between input and output. Such high gain leads to limit-cycle behaviour in the model. A high-frequency dither at the relay input acts as a stabilizing signal to deal with this problem.
