Abstract

Civil aircraft provide flight guidance during take-off. It is difficult to control the pitch angle or the speed to reach the target value with classical control method. It is necessary to study a new control method to improve flight safety, maneuverability and fuel economy. In this paper, a longitudinal dynamics model is established for civil aircraft during take-off, and the longitudinal control law of take-off guidance is designed on LQG/LTR method. Through modeling and simulation, the dynamic response characteristics of speed and pitch angle to takeoff are obtained. The results show that compared with the conventional PID control, the dynamic performance of the designed control law is improved by about 40%, and it has better robustness, especially the ability to resist gust interference.
