Abstract:

Most of the researches on the stability region of missile control parameters ignore the influence of the dynamic response process of the actuator. In this paper, the dynamic equations of the missile and the actuator are established firstly. Considering the steady-state response and dynamic response of the actuator, applying the Routh criterion, the dynamic relationship between the damping feedback gain of the non-spinning missile and the control parameters of the actuator is given. In order to deduce the stability region of the damping feedback gain of the spinning missile, the expression of the actuator in the quasi-body coordinate system is analyzed, then the dynamic stability condition of the spinning missile is given by using the complex attitude angle method and Lyapunov stability criterion. Finally, a missile flight parameter is taken as an example to verify the effectiveness of the stability conditions.

Key words: missile, damping pilot, complex attitude angle method, Lyapunov stability criterion, actuator dynamic response
