摘要：

A novel 2-DOF ammunition coordinator structure scheme is proposed, and the controlled dynamics behavior of the coordinator is studied by considering the influence of the random vibration of its installation base. The random vibration of base is treated as one kind of external disturbance forces acting on the coordinator, and the action of the coordinator on the base is negligible. On the assumption that the external disturbance force and the control force are bounded, a nonlinear control algorithm and the structure-control coupling dynamics equations of the coordinator are established based on the second kind Lagrange equations and a special implicitly given Lyapunov function. The dynamics equations are solved by a numerical algorithm based on Newton's method and the Runge-Kutta method. The simulation result shows that the proposed 2-DOF ammunition coordinator can be used to realize the accurate coordination and positioning control of the ammunitions.
