“…In literature, various nonlinear control techniques were used in aerospace applications such as target interception at desired impact time, 24 impact angle constraints, 25 impact time and impact angle constraints, 26,27 integrated guidance and control, 28 waypoint following for fixed-wing UAVs, 29 flat-spin aircraft recovery, 30 and salvo guidance. 31,32 Most of the guidance discussed so far were designed with the objective of minimizing a performance index using the optimal control design framework. However, the optimal control framework may not be robust in nature in presence of matched disturbances.…”

In this paper, cooperative guidance strategies for the survival of cooperating team of two unmanned aerial vehicles (UAVs) against two attackers are proposed. The guidance schemes are designed under the assumptions that each UAV is being pursued by one attacker without cooperation with other attacker. The guidance schemes are designed to combat attackers guided either by proportional navigation (PN) or augmented PN guidance methodologies. The attackers are lured onto a collision course with each other such that intra-attacker interception is achieved before the target UAVs are captured. Sliding mode control techniques are employed to satisfy the sufficiency conditions for the survival within a finite time. Due to the nonlinear framework used for guidance design, the proposed strategies remain effective even for the engagements with large heading angle errors. Numerical simulations are presented to demonstrate the effectiveness of the proposed guidance strategies under various engagement geometries.
