摘　　要：　为GPS在旋转火箭弹上的使用提供一种新的方案.建立了消旋平台的动力学方程,采用四阶Runge-Kutta法对控制算法进行计算机仿真.通过计算机仿真,得到了消旋平台绕纵向对称轴旋转角位移和角速度的时间响应规律.从响应曲线可以看出,只要合理地调整PD控制参数,消旋平台就可以在规定的时间内达到稳态,验证了该控制算法的正确性.To put forward a new method about GPS applying on rocket, the dynamic equations of eliminating rotartion of platform are established and the RungeKutta numerical simulation for the control arithmetic is made. The response characteristic about angular velocity and angular displacement to time for the platform is obtained. On the basis of the simulated results, the rotating movement of the platform will reach stabilization in a given time, as proper control parameters are rationally selected. The correct control arithmetic is proved.
