摘要

摘要:
针对理想复飞轨迹已知条件下的舰载机自动复飞控制问题，提出一种基于偏差模型的动态面控制（DM-DSC）算法。基于Radau伪谱法给出了舰载机着舰的最优复飞轨迹；根据得到的最优复飞轨迹及其所对应的控制方案，分别给出了速度子系统和高度子系统的偏差控制模型和反演（Backstepping）控制器，并通过引入动态面结构来获得虚拟控制量的微分信号，避免了Backstepping控制律求解过程中的“微分膨胀”问题；考虑到气动参数的不确定性及舰尾流场的干扰，采用线性扩张状态观测器（LESO）对控制模型中的干扰项进行估计和补偿，并设计抗饱和辅助系统来抑制控制饱和的不利影响；最后，基于Lyapunov方法证明闭环系统信号的有界性。仿真结果表明：所提算法具有良好的控制性能。

Abstract:
In this paper, a deviation model dynamic surface control algorithm (DM-DSC) is designed for automatic wave-off control of carrier aircraft when the optimal wave-off trajectory is available. Firstly, the optimal wave-off trajectory is given based on Radau pseudospectral method. Furthermore, according to the optimal wave-off trajectory and the corresponding control scheme, the deviation control models and Backstepping controllers of the velocity subsystem and altitude subsystem are given respectively. Then the dynamic surface structure is introduced to obtain the differential signal of the virtual control variable, and at the same time, the “differential expansion” problem in Backstepping control is avoided. Then, in order to acquire the differential signal of the virtual control variable and simultaneously avoid the "differential expansion" problem in Backstepping control, the dynamic surface structure is introduced. Considering the uncertainty of aerodynamic parameters and the disturbance of carrier air wake, the linear extended state observer (LESO) is used to estimate and compensate for the disturbance in the control model, and the anti-saturation auxiliary structure is introduced to suppress the influence of control saturation on the controller performance. Finally, the boundedness of the closed-loop system is proved based on the Lyapunov method. The comparative simulation results demonstrate that the DM-DSC algorithm has good control performance.
