Aiming at the situation constraint problem in air combat trajectory control, a constrained backstepping flight control law is proposed. This method considers the constraints of the amplitude and bandwidth of the state variables in the traditional flight process. At the same time, it also introduces the situation information of the two aircraft air combat into the control law. The correction error is defined in the control law error, and the angle situation information is used to update the correction error. When the situation is dominant, the system can perform the maneuver task normally, and the correction error converges to 0 quickly When it is a disadvantage, the correction error becomes larger, and affects the maneuver, so that the situation changes to the advantage. The simulation results show that the method can effectively make the situation change in a favorable direction during maneuvering flight.
