Global output regulation of uncertain nonlinear systems with exogenous signals. (English) Zbl 0964.93057
The paper deals with uncertain output feedback systems affected by disturbances which are generated from a known autonomous exosystem. The system uncertainty is parameterized by an unknown parameter vector which can be considered as disturbances or an exogenous signal. The author studies the global asymptotic output tracking of smooth trajectories using output feedback. The controller dynamics includes the estimation of both state variables and the unknown parameters or disturbances. It can be viewed as a generalization of adaptive algorithms. An application of the algorithm is considered.
