Multiple-model switching control based adaptive failure compensation for hypersonic vehicles

摘要

This paper develops a multiple-model switching control based adaptive failure compensation scheme for hypersonic vehicles with some stuck actuators. The system uncertainties, caused by failures and unknown inertia parameters, are first parameterized. Then multiple adaptive dynamic estimators are designed, based on which, multiple adaptive control signals are designed using an error transformation. Finally, a control switching mechanism is established to select an appropriate control signal as the applied one. Simulation results on an X-33 vehicle model are given to demonstrate the its effectiveness.
