Modern fighter aircraft have been designed to have high maneuverability in order to preoccupy strategic superiority in short-range air-to-air combat between fighter aircraft in warfare. Digital fly-by-wire flight control system design is aimed at providing good handling qualities for all mission task elements over the entire flight envelope. To provide both excellent gross acquisition and fine tracking compatibility, simultaneously for air-to-air combat maneuvers, this article presents a common longitudinal control law design of a task-dependent self-adjusting command-path pilot prefilter gain scheduler within the same control law design architecture and response type based on nonlinear dynamic inversion control. We perform the frequency- and time-domain analyses based on the mathematical model of T-50 advanced trainer aircraft to evaluate the basic flying qualities of the proposed control method. Furthermore, the pilot evaluation is performed to evaluate the gross acquisition and fine tracking capability for air-to-air tracking maneuvers in a handling quality simulator. The evaluation results reveal that the proposed control method improves the fine tracking capability without the degradation of gross acquisition.

现代战斗机的设计具有很高的机动性，以便在战斗中在战斗机之间进行短距离空空作战时占据战略优势。数字化电传飞行控制系统设计旨在为整个飞行范围内的所有任务任务要素提供良好的处理质量。为了同时提供出色的总捕获能力和良好的跟踪兼容性，同时针对空空作战演习，本文提出了一种在相同控制律范围内基于任务的自调整命令路径飞行员预滤波器增益调度器的通用纵向控制律设计基于非线性动态反演控制的设计架构和响应类型。我们基于T-50高级教练机的数学模型进行频域和时域分析，以评估所提出的控制方法的基本飞行质量。此外，执行飞行员评估以评估操纵质量模拟器中的空对空跟踪演习的总采集和精细跟踪能力。评估结果表明，所提出的控制方法提高了精细跟踪能力，而不会降低总采集量。
