带有引诱角色的多飞行器协同最优制导方法

考虑我方高价值飞行器面临对方拦截器拦截时，发射两枚防御器对拦截器进行拦截的情形。针对对方拦截器采用扩展比例导引律，在4个飞行器均具有一阶线性动力学特性假设下，基于最优控制理论设计了能在拦截末端施加相对拦截角的显式协同制导律。显式协同制导律将高价值飞行器和两枚防御器三者的协同考虑在内，给出了三者最优控制输入的解析解。仿真结果表明，设计的制导律能使两防御器成功拦截敌方拦截器，且在拦截末端施加一个相对拦截角。通过与只考虑两防御器协同的隐式协同制导律进行比较，可发现显式的协同制导律在控制要求和能量消耗上，要优于隐式的协同制导律。此外，还验证了在不同发射条件下的协同制导律的稳定性。

Cooperative optimal guidance method for multi-aircraft with luring role

This paper considers the situation that our high-value aircraft launches two defender to intercept the interceptor when it is faced with interception by the other interceptor. Based on the optimal control theory, an explicit cooperative guidance law with relative interception angle at the end of interception is designed under the assumption that all four aircraft have first-order linear dynamic characteristics. The explicit cooperative guidance law takes into account the cooperation of high-value aircraft and two defenders, and gives the analytical solution of the optimal control input of the three objects. The simulation results show that the designed guidance law can make the two defenders intercept the interceptor successfully, and impose a relative interception angle at the end of the interception. By comparing with the implicit cooperative guidance law which only considers two defenders, the explicit cooperative guidance law is superior to the implicit cooperative guidance law in control requirements and energy consumption. In addition, the stability of the cooperative guidance law under different launching conditions is verified.
