To solve the problem of accurate deformation and cooperative control of the trailing edge of variable camber wing, a deformation feedback control method combining angle sensor and fiber Bragg grating deformation sensor is proposed, and a distributed synchronous controller based on deviation coupling is designed to solve the synchronous deflection problem of the trailing edge of variable camber wing. By analyzing the variable camber wing structure, the relationship between the trailing edge deflection angle and the drive shaft deflection angle was obtained, which provided input for the control system. Through the software and hardware design of the control system, the precise control of the trailing edge deflection angle was achieved, and ground follow-up loading tests were carried out to verify the performance of the control system.

By analyzing the variable camber wing structure, the relationship between the trailing edge deflection angle and the drive shaft deflection angle was obtained, which provided input for the control system. Through the software and hardware design of the control system, the precise control of the trailing edge deflection angle was achieved, and ground follow-up loading tests were carried out to verify the performance of the control system.
