摘　　要：为了减小多弹协同时间误差,本文提出了一种基于领从式策略的新型三维时间协同制导律。不同于基于剩余时间估计实现多弹协同的领从式制导律,该制导律将对攻击时间的控制问题转化为从弹跟踪领弹的剩余弹目相对距离问题,避免了因剩余时间求解不准确而产生的时间协同误差,协同精度更高。本文针对指挥所、机场等静止目标,假设导弹速度恒定,领弹采用增广比例导引,从弹利用二阶非线性系统的有限时间收敛特性求得总控制量,其后对获得的控制量进行解耦设计,分别得到俯仰通道和偏航通道的控制量。仿真结果验证了该方法的有效性和可行性。In order to reduce the time error of multi missile cooperation,a new three-dimensional time cooperation guidance law based on the leader-follower strategy is proposed.Different from the guidance law based on residual time estimation to achieve multi missile coordination,this guidance law transforms the control problem of residual time into the problem of the relative distance between the remaining missile and target of the missile tracking leader,avoids the time coordination error caused by the inaccurate solution of the residual time,and the coordination accuracy is higher.In this paper,for static targets such as command post and airport,the leader adopts augmented proportional guidance,and obtains the total control quantity from the finite time convergence characteristics of the second-order nonlinear system.Then the decoupling design is carried out for the obtained control quantities,and the control quantities of pitch channel and yaw channel are obtained respectively.Simulation results verify the effectiveness and feasibility of the method.
