Hypersonic aircraft have great potential and value in military, civil and economic terms. However, the existence of strong coupling, uncertainty, failure and other problems brings great challenges to the design of its controller. In order to solve the coupling problem between height and speed as well as increase the reliability and practicability of the controller, this paper designs a multi-input and multi-output fault-tolerant tracking controller for the longitudinal model of the hypersonic aircraft with uncertain parameters and faults. First of all, the model pretreatment is carried out, that is, the original model is transformed into a standard form of a high-order fully actuated system. At the same time, a direct input-output relationship is also established, so as to further design the basic control law according to the theory of the high-order fully actuated system; use the adaptive control principle to design parameter adaptive law to complete the estimation of uncertainty parameters. And the fault tolerance work of the fault, so that the tracking error of the system can eventually tend to zero. The Lyapunov stability theorem is used to prove the stability of the designed system; finally, the feasibility of the control law is verified through simulation.
