In order to solve the problem of control assignment caused by overdrive during tilting transition of a tiltrotor vehicle, the maneuvering contribution degree model is established. Considering the motor power and steering engine servo’s bandwidth constraints, the quantitative evaluation index of steering contribution is considered by combining the control effectiveness and the coupling efficiency, and the control contribution is calculated according to the control contribution. The optimal generalized control assignment strategy for each control channel is formulated by degree ordering from high to low, and the tilting control law can track the transition trajectory accurately.

The optimal generalized control assignment strategy for each control channel is formulated by degree ordering from high to low, and the tilting control law can track the transition trajectory accurately.
