摘　　要：针对导弹有视场角约束、攻击角度约束以及攻击时间约束等多约束条件下的制导问题,基于虚拟命中点策略,提出了一种两阶段三维空间多约束协同制导律。基于障碍李雅普诺夫函数,设计了满足视场角约束的期望攻击角度的三维制导方案。利用快速迭代算法构造出满足期望时间约束的虚拟命中点,将制导过程分为满足视场角约束的期望攻击角度制导(FOV-constrained IACG)和比例导引制导(PNG)两个阶段。基于空间交战几何关系,给出了等效最大视场角计算方法,保证视场角全程满足约束。分析表明,当满足攻击角度约束和攻击时间约束后,对于静止目标可采用PNG制导继续满足上述约束。仿真结果表明,所提出的制导律能够解决三维空间中多弹对静止目标的期望攻击角度及时间,且满足视场角约束的协同攻击问题。In order to satisfy multiple constraints such as field-of-view(FOV),desired impact angle and time,a two-stage three-dimensional cooperative guidance law is proposed based on virtual point.A FOVconstrained three-dimensional guidance law based on barrier Lyapunov function that can achieve desired impact angle is designed.A virtual point satisfying the impact time constraint is constructed by a rapid iteration algorithm.As a result,the proposed guidance law can be divided into two stages including the impact angle control guidance stage with FOV constraint(FOV-constrained IACG)and the proportional navigation guidance(PNG)stage.For holding FOV constraint throughout the whole engagement progress,the concept of equivalent maximum FOV and corresponding calculation method based on space geometry of engagement are proposed.The analysis shows that,PNG can maintain the above three constraints for a stationary target when the constraints of desired impact angle and time are satisfied.The simulation results indicate that the proposed guidance law can solve the problem of simultaneous attack against a stationary target in desired impact angle with FOV constraint in three-dimensional space.
