Abstract :
This paper presents the L1 adaptive controller for a class of multi-input multi-output nonlinear systems in the presence of unmatched uncertainties. The L1 controller ensures uniformly bounded transient response for system´s input and output signals simultaneously, in addition to steady-state tracking. Simulation results verify the theoretical findings.
