Distributed cooperative guidance law for multiple flight vehicles of saturation attack

A distributed cooperative guidance law for multiple flight vehicles of saturation attack is proposed. According to the characteristics of multiple flight vehicles saturation attack, problem of cooperative guidance is converted to the consensus of multiple flight vehicles. A cooperative guidance scheme based on finite time consensus theory is proposed, which contains two key technologies. One is design the perpendicular acceleration command to ensure the convergence of the relative distance, another is develop the acceleration command along the line-of-sight (LOS) based on the finite time consensus theory, to ensure time-To-go of vehicles reach to consensus. The control input constraint is further considered, and the process of proving the stability in this condition is given. Numerical simulation was carried out using the control protocol in and out the presence of control input constraint, respectively. Simulation results show that the proposed method could realize the saturation attack under the effect of two control protocol, but the consensus time will be longer with control input constraint.
