A designing method of controlled selector with nonlinear inversion transformation is proposed, which is successfully applied to control system for advanced short takeoff and vertical landing(ASTOVL). The main idea of the method is, based on the theory of nonlinear inversion transformation, that syncretizing control of multi aerodynamic rudder and multi thrust vector rudder is implemented to distribute the force and moment on the fighter with reason. This method overcomes the deficiency of traditional ways and makes design methods simply to be implemented in practice. At last the simulation analysis of decelerating transition for ASTOVL shows that controlled selector designed possess the favorable flying qualities in the low speed performance envelope.
