A cooperative salvo guidance strategy using fixed finite-time consensus is proposed here. The consensus algorithm is based on sliding mode control. The cooperative salvo attack problem is transformed to a consensus problem over a cycle digraph. This aids in designing a guidance strategy through selection of heterogeneous gains. The proposed strategy guarantees convergence to a common impact time for all the interceptors, within a fixed time, from a wide range of initial heading angles. Subsequently, the guidance strategy is extended to cooperatively intercept a constant velocity target. The efficacy of the proposed algorithm is vindicated through simulations on both stationary and constant velocity targets. Numerical simulations are also performed on realistic missile models that account for aerodynamic parameter variations, yielding satisfactory performance.

在有向循环上使用有限时间共识的协同齐发引导

这里提出了一种使用固定有限时间共识的协同齐发制导策略。共识算法基于滑模控制。协同齐发攻击问题转化为循环有向图上的共识问题。这有助于通过选择异质增益来设计指导策略。所提出的策略保证所有拦截器在固定时间内从广泛​​的初始航向角收敛到共同的撞击时间。随后，制导策略扩展到协同拦截等速目标。通过对静止和恒速目标的仿真证明了所提出算法的有效性。还对考虑空气动力学参数变化的真实导弹模型进行了数值模拟，
