Attitude control based on the all channel-coupled characteristic model for hypersonic vehicles

Considering that attack angle, sideslip angle and roll angle have obvious coupled feature, a dynamic model of "X-20-like"hypersonic vehicles is established in this paper firstly, then an all channel-coupled characteristic model considering coupled states and coupled inputs be proposed. After that, a controller combined with multivariate golden section adaptive control law, logical derivative control law and integral control law is designed. At last, the tracking ability and robust ability of the controller are approved by simulation of the interference model. Simulations also show that the all channel-coupled characteristic model controller is better for attitude control of hypersonic vehicles than the single channel one.
