计及弯折波的舰载机拦阻过程控制
张萍，金栋平
摘要:本文计入弯折波，用PID控制方法研究了舰载机拦阻着舰过程中的动力学问题。鉴于弯折波在甲板滑轮与钩索啮合点之间反复传播的复杂性，首先不考虑弯折波，以液压阻尼力作为控制输入建立系统非线性动力学模型，按照尽可能使拦阻钩载保持常数这一要求，用最优控制方法获得了一组理想轨迹。然后，用PID控制方法进行跟踪控制，跟踪过程中采用了离散的弯折波模型。结果表明，弯折波的计入，会使拦阻钩载在拦阻初期出现波动效应，这与美军标MIL-STD-2066中的实验结果一致。

Carrier Aircraft Arresting System Control Considering Kink-Wave
Ping Zhang, Dongping Jin
Abstract：Taking kink-wave into account, the dynamic response of carrier aircraft during an arrested landing was studied by using PID control method. As it is a complex process of kink wave propagating repeatedly between the deck sheave and the hook, the nonlinear continuous mathematical model without regard to kink-wave was established, in which considering the hydraulic damping force as an input. Then, a set of ideal trajectory was found with optimal control method to make the hook load a constant as much as possible. Afterwards, the ideal response trajectory was tracked through using PID control method. During the tracking process, a discrete kink-wave model was used. The result shows that when taking kink-wave into account, the hook load will vibrate at the initial period of the arresting process, which is consistent with the experimental result of the American military standard MIL-STD-2066.
