Cooperative target capture using predefined-time consensus over fixed and switching networks

We propose predefined-time consensus-based cooperative guidance laws for a swarm of interceptors to simultaneously capture target capable executing various kinds motions. Unlike leader-follower techniques, the has no leader and each interceptor executes its own command in distributive fashion, thus obviating residency mission over single interceptor. first design commands subject target's mobility, followed by same when is stationary, also account interceptors' changing topologies. further show through rigorous analysis that proposed guarantee consensus time-to-go values within predefined-time. The allows feasible time be set arbitrarily at will during regardless initial values, thereby ensuring simultaneous interception . demonstrate efficacy via simulations connected static dynamic networks.
