Adaptive Critic Based Control of Aircraft with Atmospheric Disturbance

The design of fight control is full of challenges because of the complex model and the complicated fight environment. The traditional control methods no longer ensure the demand in the many fight modes. Advanced control methods attract more and more researchers to make application research in this field. Adaptive critic design (ACD) is an effective control method to learn the optimal control online. The performance of fight control with atmospheric disturbance needs to be improved using active control or robust control. This paper presents adaptive critic based controller design of aircraft with atmospheric disturbance. The controller does not rely on the parameters of the aircraft, and it can learn online very well. When there are atmospheric disturbances, such as random turbulence, discrete gust and wind shear, adaptive critic based controller can resist the disturbances effectively, and shows the good robust performance. Finally, the simulation proves the validity of the adaptive critic based controller for aircraft with atmospheric disturbance.
