【摘要】：舰载战斗机是航空母舰武器系统中的重要作战手段，为保证舰载机安全着舰，提出了进场功率补偿系统，按照进场功率补偿控制律对发动机推力进行控制，以克服舰载机低速进场时的速度不稳问题，提高航迹控制精度。因此，研究并设计进场功率补偿系统具有重要意义。本文以国外某舰载机为例，展开了进场功率补偿控制律的研究和设计，主要研究内容如下： 1.舰载机纵向运动数学模型的建立和处理。根据牛顿运动定律对舰载机纵向运动受力分析，列出了其动力学方程，对其进行小扰动和线性化的简化处理，建立舰载机三自由度的纵向运动模型，从而得到航迹角对俯仰角的一般响应特性。 2.舰载机进场功率补偿的控制策略研究。分别分析了速度恒定的进场功率补偿系统和迎角恒定的进场功率补偿系统，应用PID理论进行设计并比较其控制性能，结论是迎角恒定的进场功率补偿系统比速度恒定的进场功率补偿系统更能满足舰载机着舰快速性、准确性和安全性的要求。 3.舰载机进场功率补偿控制律的分析和设计。针对国外某型舰载机的具体要求，，采用引入了法向加速度和舵面信息的迎角恒定的进场功率补偿系统，并进行控制律的分析和设计。通过仿真验证表明，所设计的进场功率补偿控制律能够良好的满足该型舰载机的要求，保证其着舰的安全性和稳定性。 通过分析和仿真验证表明，本文所设计的自动油门指令算法和进场功率补偿控制律达到了该型舰载机的各项要求，具有一定的工程实际意义。
[Abstract]:Shipborne fighter is an important means of combat in aircraft carrier weapon system. In order to ensure the carrier aircraft to land safely, an approach power compensation system is proposed to control the engine thrust in accordance with the approach power compensation control law. In order to overcome the problem of velocity instability and improve the accuracy of track control. Therefore, it is of great significance to study and design the approach power compensation system. Taking a shipborne aircraft abroad as an example, the research and design of approach power compensation control law are carried out in this paper. The main research contents are as follows: 1. Establishment and processing of Longitudinal Motion Mathematical Model of Carrier-borne aircraft. According to Newton's law of motion, the longitudinal motion force of shipborne aircraft is analyzed, its dynamic equation is listed, the small disturbance and linearization are simplified, and the longitudinal motion model of shipborne aircraft with three degrees of freedom is established. The general response of track angle to pitch angle is obtained. 2. Research on Control Strategy of approach Power compensation for Carrier aircraft. The power compensation system with constant velocity and constant angle of attack is analyzed, and the control performance is compared by using PID theory. The conclusion is that the approach power compensation system with constant angle of attack can meet the requirements of speed, accuracy and safety better than the one with constant speed. 3. Analysis and design of power compensation control law for shipborne aircraft. According to the specific requirements of a shipborne aircraft abroad, a power compensation system with constant angle of attack with normal acceleration and rudder surface information is adopted, and the control law is analyzed and designed. The simulation results show that the proposed approach power compensation control law can meet the requirements of the aircraft and ensure the safety and stability of the ship landing. The analysis and simulation results show that the automatic throttle instruction algorithm and the approach power compensation control law designed in this paper meet the requirements of the shipborne aircraft and have a certain practical significance in engineering.
