A new structure actuator for reducing the coupling of BTT missiles is studied. The new structure actuator can roll independently along the longitudinal axis of the missile. The actu- ator instead of airframe needs to steer when controlling BTT missile roll. So the rolling speed of main airframe and thus the coupling of missile introduced by airframe rolling are reduced. And control logic is designed for the missile using roll actuator. Finally, analysis and simulation results demonstrate the effectiveness of the rolling actuator in decoupling a BTT missile.展开更多

By employing general parametric solutions to a type of so-called high-order Sylvester matrix equations, complete parametric control approaches for high-order linear systems are presented. The proposed approaches give simple complete parametric expressions for the feedback gains and the closed-loop eigenvector matrices, and produce all the design degrees of freedom. Fur-thermore, important special cases are particularly treated. Based on the proposed parametric design approaches, a parametric method for the gain-scheduling controller design of a linear time-varying system is proposed and the design of a BTT missile autopilot is carried out. The simulation results show that the method is superior to the traditional one in sense of either global stability or system performance.展开更多
