This paper uses the modified Backstepping (BS) Control method and the Dynamic Control Allocation (DCA) method to solve the problem that when the fighter aircraft under different flight conditions, it will be adaptively tracking different commands. Firstly, we introduce the classical Lyapunov method and classical backstepping control method, and then propose a modified backstepping control method to be applied by general flight control system model. Finally, for the problem that the common control allocation method can't compensate for ignoring the actuator dynamics, a dynamic control allocation method is introduced, and it is successfully applied to the design of the whole closed loop control system. The controller reserves the stable nonlinear term of the system, eliminates the unstable nonlinear term, and minimize the impact of ignoring the actuator dynamic through the dynamic allocation. The simulation results show that the methods in this paper have a good response. It can be implemented in different flight conditions with a good performance of command tracking and lots of robustness.
