一种攻击机动目标的变结构导引律研究

无人机在快速接敌的过程中,传统比例导引法系数的最优解与目标和载机的距离有关,而且一旦目标机动或增加了干扰,跟踪效果都会变差.为了解决这一问题,提出了一种变结构的跟踪方法.仿真结果表明:该方法在未知目标距离的情况下能够快速接敌,且能减小无人机所需过载,提高制导精度和跟踪鲁棒性,限制了视线角速度.

A Guidance Law of Variable Structure Adaptive Research for Target Escape with Acceleration

In the course of UCAV approach to the enemy plane,the beast coefficient of tradition proportion lead law is related to target and UCAV's distance,and if target move with high acceleration or have disturb,the result will became bad.For resolve this question,this paper given a variable structure adaptive method.The simulation result show that the method not only resolve the question of quickly approach to the enemy plane,but also reduce the overload of the UCAV,improve guiding precision and robust,restrict th...
