摘要：AbstractIn this paper, Fault Tolerant Model Reference Adaptive Control (FT-MRAC) is designed for an actuator fault airship model. First, a modal analysis of the nominal plant model is presented. Post-fault airship model including various actuator faults and external disturbance, followed by derivation and stability analysis of FT-MRAC are presented. Simulation results are presented for two actuator fault scenarios, viz. actuator lock and actuator efficiency loss, and compared with fixed gain control law against the reference state trajectories. Results show efficacy of the FT-MRAC in terms of ability of the airship recovery to a steady state condition with desired transients characteristics in the event of actuator failure.
