Abstract

In this paper, the problem of robust attraction for an affine nonlinear control system with uncertainties is studied. For this system, we contract the feedback control law which makes the corresponding closed-loop system be finitely attracted by a given neighborhood of equilibrium state. The feedback control law consists of two parts: The first one is a nonlinear control law of which the role is to make the nominal nonlinear closed-loop system be exponentially stable. This is in fact a static control law in the form of state feedback; the second one is a dynamic compensatory control law of which the role is to attenuate an influence of uncertainties on system stability
