This paper designs the feedback controller for the unstable Dutch Roll and severe kinematic coupling of the hypersonic vehicle at high angle of attack and large mach number. This paper deduces the mechanism of improving the stability of the Dutch Roll and illustrates the mechanism of restraining the kinematic coupling using controller based on the linear small perturbation equations. And an easy analysis is made about the signal of controller. Finally, the relational tests are conducted in simulations using controller. The simulation result shows that the controller can improve the damp of the Dutch Roll, weaken the influence of kinematic coupling, restrain the variety of sideslip and improve the equality of sideslip.
