论文摘要
在这项研究中，开发了代表飞机纵向飞行动力学的线性数学模型，并研究了飞机在微库中的响应。试图用飞机的电梯控制表面抑制微库的作用，这是由线性二次调节器法控制的。为了说明所提出的控制方法的有效性，进行了大量的模拟研究。通过模拟的结果，观察到微肉变对俯仰角和高度的影响会通过提出的控制方法显着减弱。此外，可以证实，提供必要的控制器输入的电梯控制表面运动在飞机的物理能力之内。
In this study, a linear mathematical model representing longitudinal flight dynamics of an airplane is developed and responses of the aircraft during a microburst encounter are investigated. The effects of microburst that are acting on the aircraft are attempted to be suppressed with the elevator control surface of the aircraft, which is controlled by Linear Quadratic Regulator method. To illustrate the effectiveness of the proposed control method, numerous numbers of simulation studies is performed. As a result of the simulations, it is observed that effects of microburst on the pitching angle and altitude are significantly attenuated by the proposed control method. In addition, it is confirmed that the elevator control surface movement which provides the necessary controller input is within the physical capabilities of the aircraft.
