摘要
A feasible target searching strategy together with a novel attitude control scheme for kinetic kill vehicle are presented for targeting searching problem at the beginning of terminal guidance phase. Error quaternion is introduced to establish the mathematical models of attitude motion and the requirements of attitude control are analyzed. The designed searching strategy is composed of deflections and rotations and can effectively avoid missing some searching regions. Feedback linearization method is used to deal with the nonlinear systems and terminal sliding mode control is adopted to guarantee time constraint and precision of attitude control. High quality performances of the proposed control scheme are demonstrated by the numerical simulations compared with the PD controller.
