Investigation On Design Of Missile Control System

The task of the missile control system is to guide the missile to the object, then smash it. The missile control system composed of two pares, the controller and the controlled object. But different kinds of missile have different control system and loops. The different kinds of missile have analogical loops as the control system is, constituted on the theory of automatic control. The central contents in this paper is the design of a certain missile, this research is practical.The central contents in this paper is: first, the reference frame is defined and the movement equation and the transfer function of the body are proposed in portrait plane. So the module of the center of mass stabilization loop is proposed. Second, the damp loop and the center of mass stabilization loop are simulated by traditional PID control theory, the problem lied in the application of the PID control theory is analyzed. Third, the center of mass stabilization loop is designed by the proportion control law in variable structure control, the design method of the proportion control law is deducted elaborately. The result is the character points is unified on parameter. The two simulation results of the different methods are compared in this paper. Last, the interfere restrain of the two methods is discussed.The conclusion of the paper has real significance and bright future.
