Fighter aircraft often require unconventional maneuverability that civil aircraft cannot perform. The conventional flight control devices are not sufficient for this maneuver. Thus, to be able to perform unconventional maneuvers, additional control devices may be required, such as the thrust vectoring system (TVS). This paper will discuss the effect of TVS implementation in improving maneuverability. In this work, a dynamic model of F-4 Phantom is used as the basis for the study. The dynamic model of the aircraft with TVS is constructed analytically and numerically. The nonlinear model obtained from the modeling process then linearized at a particular flight condition and some TVS deflection values. Further, the linear system and control approach is employed for evaluating and designing the linear controllers for stabilization and maneuvering tasks. The closed-loop system, which is implemented in the MATLAB/Simulink environment, then numerically simulated and observed for analyzing the effect of implementing different TVS deflection on the required control effort in high angle of attack maneuvers. The simulation results show that the TVS can affect the performance of the closed-loop system in stabilization tasks. While at some deflection values, TVS can also help to reduce the required control effort to tracking attitude reference command when executing the high angle of attack maneuvers.

战斗机往往需要民用飞机无法执行的非常规机动性。传统的飞行控制装置不足以完成这种机动。因此，为了能够执行非常规机动，可能需要额外的控制设备，例如推力矢量系统 (TVS)。本文将讨论 TVS 实施在提高机动性方面的效果。在这项工作中，F-4 Phantom 的动态模型被用作研究的基础。采用分析和数值方法构建了带有 TVS 的飞机动力学模型。从建模过程中获得的非线性模型然后在特定飞行条件和一些 TVS 偏转值下线性化。更远，线性系统和控制方法用于评估和设计用于稳定和机动任务的线性控制器。在 MATLAB/Simulink 环境中实施的闭环系统，然后进行数值模拟和观察，以分析实施不同 TVS 偏转对大迎角机动所需控制力的影响。仿真结果表明，TVS 会影响闭环系统在稳定任务中的性能。在某些偏转值下，TVS 还可以帮助减少执行大迎角机动时跟踪姿态参考命令所需的控制工作。然后进行数值模拟和观察，以分析在大迎角机动中实施不同 TVS 偏转对所需控制力的影响。仿真结果表明，TVS 会影响闭环系统在稳定任务中的性能。在某些偏转值下，TVS 还可以帮助减少执行大迎角机动时跟踪姿态参考命令所需的控制工作。然后进行数值模拟和观察，以分析在大迎角机动中实施不同 TVS 偏转对所需控制力的影响。仿真结果表明，TVS 会影响闭环系统在稳定任务中的性能。在某些偏转值下，TVS 还可以帮助减少执行大迎角机动时跟踪姿态参考命令所需的控制工作。
