摘要：AbstractA Nussbaum adaptive fault-tolerant controller is designed for the longitudinal motion of a twin-engine hypersonic vehicle containing uncertain parameters and unexpected actuator faults. We first apply feedback linearization to design the controller under nominal condition. Through a combination of parametrization and adaptive law, the model uncertainty can be well coped with. And Nussbaum gain method is used to solve the uncertain control direction function. Based on the previous work, considering the existence of throttle faults, a fault-tolerant controller is developed by choosing the appropriate range of the controller parameters, which is defined to compensate the actuator faults. Simulation results confirm the effectiveness of the proposed design.
