Distributed leaderless cooperative guidance for multiple missiles with time delay and switching topologies

The problem of leaderless multiple missiles simultaneously attacking a stationary target under fixed time delay and switching directed communication is investigated in this paper. We firstly transform the missile guidance system into an equivalent system. Then based on the equivalent system, we design two distributed cooperative guidance laws in LOS direction and normal direction of LOS, respectively. The two cooperative guidance laws mentioned above use local neighbouring communications where fixed time delay and switching directed communication are taken into account. The former guidance law can ensure missiles’ time-to-go converge to consensus asymptotically. The later guidance law can ensure missiles’ relative LOS angle errors converge to zero asymptotically. Using the linear matrix inequalities (LMIS) technology, we derive the sufficient conditions of the proposed cooperative guidance laws. Simulation results demonstrate the effectiveness of the proposed cooperative guidance laws.
