Abstract :
Direct adaptive control schemes to achieve state or output tracking are developed for linear time-invariant plants with actuator nonlinearities and failures. Conditions and controller structures for achieving plant-model state or output matching are presented. Adaptive laws are designed for updating the controller parameters when the plant parameters, actuator nonlinearity and failure parameters are unknown. The effectiveness of the proposed designs is illustrated with simulation results
