摘要

The fault-tolerant anti-disturbance control problem for air-breathing hypersonic vehicles with variable geometry inlet (AHV-VGI) is investigated. The VGI technique enlarges the AHV flight envelope at the expense of the system to inevitably possess unknown disturbances, model uncertainties and actuator faults. A novel fault-tolerant control strategy is proposed under the back-stepping control scheme based on extended state observer (ESO) and dynamic inversion. In each step, two ESOs are designed. The first one estimates the virtual control signals, and the second one approximates the total uncertainties. Dynamic inversion is introduced into the controller to deal with the non-affine actuator faults. In particular, the ESOs are activated successively in the designed controller. ESO estimation errors and output tracking errors of the AHV-VGI system are proved to be arbitrarily small in theory. Simulation results are provided to demonstrate the effectiveness and superiority of the proposed control strategy.
