理想着舰点的垂直运动是影响着舰精度和安全的一个主要因素,因此必须加强舰载机对理想着舰点垂直运动的同步跟踪能力。为此,提出对理想着舰点垂直运动的位置和速度信号进行预估和补偿的方法,将垂直运动的位置和速度信号经过预估和补偿后分别引入到纵向自动着舰引导系统和飞控系统的垂向速度通道中,使得舰载机可以准确跟踪理想着舰点的垂直运动,以减小甲板运动对着舰的影响。针对不同海况条件,对设计的补偿器和预估器进行仿真验证,并与其他方法进行比较。结果表明本文提出的理想着舰点垂直运动预估与补偿方法可有效地补偿由甲板运动引起的着舰误差,显著提高了着舰的安全性和精确性。
The vertical movement of the ideal landing point is one of the main factors that affect the accuracy and safety of the ship. Therefore, it is necessary to enhance the tracking capability of the carrier-based aircraft for the vertical movement of the ideal landing point. Therefore, a method of estimating and compensating the position and velocity signals of the vertical movement of the ideal landing point is proposed. The position and velocity signals of the vertical movement are estimated and compensated and then introduced into the longitudinal automatic guided ship guidance system and the flight control The vertical velocity of the system makes the carrier aircraft accurately track the vertical movement of the ideal landing point to reduce the impact of deck movement on the ship. For different sea conditions, the designed compensators and predictors are validated and compared with other methods. The results show that the proposed method for estimating and compensating the vertical movement of an ideal landing point can effectively compensate for the landing error caused by the deck movement and significantly improve the safety and accuracy of the landing.
