Adaptive fault-tolerant cooperative guidance law for simultaneous arrival

The problem of simultaneous arrival is investigated in this paper for multiple interceptors under partial actuator effectiveness. A fault-tolerant cooperative guidance is presented, in which an adaptive law is designed for disposing of the uncertainty. The convergence analysis demonstrates that the simultaneous arrival could be achieved in fixed-time interval under the actuation failures. The upper bound of convergence time is not dependent on the initial conditions of interceptors. The simulation results validate the effectiveness of proposed cooperative guidance law satisfactorily.
