摘要
针对网络通信时滞条件下多飞行器博弈对抗问题,提出了一种协同微分制导律。首先,基于微分对策理论在传统的范数型性能指标基础上,设计增加权重系数,推导出一种具有“bang-bang”结构的协同微分制导方法;其次,考虑到拦截器之间的网络通信存在时滞性,导致得到的目标加速度值与实际加速度值存在误差,通过引入观测目标加速度方向信息可以减少目标加速度可达域范围,减少与目标实际加速度之间的误差,从而提高拦截器的制导精度;最后通过数值仿真验证算法的有效性。仿真结果表明该制导律不需要提前假设目标的机动规律,且在信息时滞下能有效地拦截机动目标。
Aiming at the problem of multi⁃aircraft game confrontation under the condition of network com⁃munication delay,a cooperative differential guidance law is proposed.Firstly,based on the differential countermeasure theory on the basis of the traditional norm⁃type performance index,the weight coefficient is designed to increase the weight coefficient and a collaborative differential guidance method is derived under“bang⁃bang”structure.Secondly,by considering the time delay in the network communication among in⁃terceptors,the target acceleration value obtained is an attainable domain instead of an accurate value,and the target acceleration range can be reduced by introducing the observed target acceleration direction infor⁃mation,and the error between the target acceleration and the target actual acceleration can be reduced,thus,the guidance precision of the interceptor is improved.Finally,numerical simulation is implemented to verify the effectiveness of this algorithm,and the simulation results show that this guidance law does not need to assume the maneuvering law of the target in advance and can effectively intercept the maneuvering target under the information time delay.
