针对高速飞行器编队队形切换系统，本文提出了一种基于性能函数的有限时间控制方法，以实现高速飞行器编队在动态任务场景下快速稳定切换队形。首先，建立了包含领导者和跟随者的编队动力学模型，并设计了一种新型的基于有限时间的协同控制器，从而保证在每一模态下快速收敛至期望队形。其次，为应对任务变化引发的编队切换，引入了性能函数与驻留时间联合判断机制。该机制通过实时评估系统状态，并结合驻留时间约束，确保仅当系统状态满足性能要求且驻留时间条件得到满足时，才触发队形切换，以有效保障切换过程的平滑过渡及全局稳定性。最后，通过仿真结果验证了此编队切换方法的有效性与可靠性。

For high speed aircraft formation switching systems, this paper proposes a performance function-based finite-time control method to achieve rapid and stable formation switching in dynamic mission scenarios. First, a formation dynamics model comprising a leader and followers is established, and a novel finite-time cooperative controller is designed to ensure rapid convergence to the desired formation in each mode. Second, to address formation switching triggered by mission changes, a joint decision mechanism integrating performance functions and dwell-time constraints is introduced. This mechanism evaluates the system state in real-time and incorporates dwell-time constraints, ensuring switching is triggered only when both performance requirements are satisfied and dwell-time conditions are met. This design effectively guarantees smooth transitions and global stability during the switching process. Finally, simulation results validate the effectiveness and reliability of the proposed formation switching method.
