摘　　要：为了提高导弹精确打击目标的能力,控制攻击时间和攻击角度三维制导问题在实际应用中具有重要的意义。针对这一问题,本文基于三维矢量制导模型提出了一种视场角约束下的攻击时间和攻击角度控制律。首先,通过将平面矢量制导律扩展至三维空间,提出了一种三维矢量攻击角度约束制导律;其次,在上述制导指令的拦截分量中引入剩余时间偏置项,设计了一种在视场角约束下的三维矢量制导律,并进行了稳定性分析。保证导弹能在视场角约束的条件下,以期望的攻击时间和角度击中目标,并且误差均小于0.01;最后,通过数值模拟验证了所设计制导律的正确性和有效性。In order to enhance the precision of missile strikes on targets,controlling the three-dimensional gui-dance problem involving attack time and attack angle is of significant importance in practical applications.For addressing this problem,this paper proposes a control law for attack time and attack angle under field-of-view constraints based on the three-dimensional vector guidance model.Firstly,by extending the planar vector guidance law to three-dimensional space,it introduces a three-dimensional vector attack angle constrained guidance law.Secondly,incorporating a residual time bias term into the interception component of the above guidance command,it designs a three-dimensional vector guidance law under field-of-view constraints,and performs the stability analysis.This design ensures that the missile can hit the target with the desired attack time and attack angle within the constraints of the field of view,with errors less than 0.01.Finally,the correctness and effectiveness of the designed guidance law are validated through numerical simulations.
