Abstract

Adaptive control Approximation methods Feedback control Linear systems Lyapunov methods Vectors
In this paper, we achieve the semi-global practical stabilization of some nonlinear sampled-data feedback control systems with unknown parameters. Our controller design is based on the higher order approximations of the exact discretized associated systems together with an over parametrization used for the adaptive law, which is due to the appearance of powers series of the unknown parameters in the analytic development of the exact discretized systems.
