Abstract

Abstract: Based on the fly height control method of modal direct switching, after the input of the control command, the control output may be oscillated or even diverged. The power function conforms to the variation law of the flight altitude command, and is used as the prototype function to derive the relationship between the given height, the current height and the vertical velocity. Using this transformation relationship as the input command of the vertical velocity control loop, a smooth control system is designed. The system does not require control modal switching and can achieve the flight altitude maintenance andflight altitude change. The performance analysis of the designed smooth control system is carried out by the A320 flight simulation platform. The results show that the system can achieve a high degree of smooth control and the steady-state error is well suppressed.
