Abstract: Considering that attack angle, sideslip angle and roll angle have obvious coupled feature, a dynamics model of “X20like”hypersonic vehicle 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 multiinput multioutput (MIMO) golden section adaptive control law, derivative control law and integral control law is designed for the system. At last, tracking ability and robustness of the controller are approved by simulations of both accurate model and 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.

Key words: hypersonic vehicles, characteristic model, adaptive control, coupled system
