多 BTT 导弹滚转通道姿态约束下的固定时间 姿态协调控制

In view of the consensus safe control problem for roll channels of multiple bank-to-turn (BTT) missiles under attitude constraints, a distributed fixed-time attitude-coordination controller is proposed. Due to the significant variation in aerodynamic parameters and high maneuvering requirements of BTT missiles, as well as practical constraints on missile attitudes, the controller is required to have high response speed and strong ability of disturbance rejection. Within this context, a distributed fixed-time attitude coordination control law for the roll channels of multiple BTT missiles is proposed, which utilizes the fixed-time control technology, barrier Lyapunov function technology, and coordinated control theory of multi-agent systems. Under this coordination control law, the roll angles of all BTT missiles converge consistently to a given reference command signal within a fixed time and in the meanwhile satisfy the attitude constraints during the whole control course. Simulation results demonstrate the effectiveness of the proposed method.
