Distributed Collaborative Active Defense Guidance for TADs System via NMPC

This paper establishes the cooperative active defense mathematical model and the distributed guidance strategy of TADs system in the two-dimensional scenario. The TADs system has a target, an attacker and multi defenders, which is different from the traditional three-body TAD system. The distributed guidance strategy makes the target and the defenders to cooperatively intercept the attacker and cover its escape region. In addition, nonlinear model predictive control (NMPC) is used to solve the problem. The guidance strategy considers the realistic model of TADs system, the defenders and target input constraints, and the target safety domain constraints. The NMPC method is used to optimize and calculate the cooperative input quantity of the target and the cooperative proportional coefficients for the defenders. The simulation results show that the distributed guidance strategy can realize the cooperative active defense guidance of the target and the defenders in the TADs system and realize the interception and escape region coverage of the attacker.
