Abstract :
Two direct adaptive control schemes are developed for parametric-strict-feedback nonlinear systems with unknown actuator failures, based on matching designs for two actuation models. Using a backstepping design technique, adaptive state feedback control laws are proposed to achieve asymptotic output tracking and ensure closed-loop signal boundedness, despite the presence of unknown actuator failures and unknown parameters
