飞机拦阻过程的非线性最优控制

 在假设拦阻力完全由阻拦索提供的前提下，建立了包含阻拦索线弹性变形的飞机拦阻过程非线性动力学模型。为使原二阶微分方程系统易于控制，使用了高一阶的模型。基于高斯伪谱方法（GPM）对飞机和阻拦索接触后的降速曲线进行了优化，并应用反馈线性化闭环跟踪优化之后的降速曲线。结果表明，阻拦索的弹性对阻拦效果有很大影响，并且反馈线性化可弥补非线性最优化在实际应用中的缺陷。

Nonlinear Optimal Control of Aircraft Arresting Process

Equations of motion of the aircraft arresting process taking the elasticity of the arresting cable into consideration were derived with the assumption that the arresting force was completely provided by the tension of the arresting cable. In order to make the original second order ordinary differential equation (ODE) system controllable, a higher order ODE was applied. After the deceleration curves were optimized using Gauss pseudospectral method (GPM), a close loop control method was employed in tracking t...
