Multiagent Pursuit-Evasion Game Control Based on Inter-Satellite Communication Link Attacked

In this paper, the resilient control strategy design of multi-agent pursuit-evasion game problem for a class of discrete-time linear time-invariant systems is studied. The communication link between the studied multi-pursuer systems is vulnerable to network attacks. This paper considers that the multi-pursuer inter-satellite link is attacked by false data injection. In the context of non-cooperative game, the control strategy of the pursuers is designed to tolerate false data injection attacks. First, an upper bound is derived from the cost function of each pursuer. Then, the upper bound is unilaterally minimized by iteratively solving a convex optimization problem, and then the resilient control strategy of each pursuer is obtained according to some coupled backward Riccati-like recursive solutions. And the evader is not affected by the cyber attack, so its control strategy can be obtained by minimizing its own cost function. Finally, a numerical example is given to verify the effectiveness of the method.
