The Research on Optimal Proportional Navigation Guidance with Single Dynamic Lag

建立具有一阶动力学滞后的制导系统模型,利用最优控制理论,推导了考虑一阶制导动力学滞后的最优制导律。与经典的比例导引、增强型比例导引进行了对比研究,研究结果表明,这种最优制导律能有效降低弹道末端对加速度的要求,减少制导系统对末导时间的要求,同时也能有效降低动力学滞后对制导系统脱靶量的影响。

The guidance model with single dynamic lag was established.The optimal guidance law with single time constant was deduced using optimal theory.The research on proportional navigation,augmented proportional navigation and optimal guidance law was done.It is concluded that the optimal guidance law with single time constant can reduce the demand of acceleration at the terminal of the trajectory and reduce the demand of guidance time,and this optimal guidance law can reduce the influence of dynamic lag on miss distance.
