Abstract

This paper presents the L₁ adaptive control architecture for nonlinear strict feedback systems in the presence of unknown high frequency control gain and unknown time-varying nonlinearities.We prove that the L₁ adaptive control architecture ensures guaranteed transient response for system´s input and output signals simultaneously. Simulations of an airplane short period dynamics verify the theoretical findings.
