摘要：

针对舰载机着舰的纵向非仿射模型,考虑舰尾流扰动的影响,提出基于非仿射模型的预设性能的控制律方法。与传统反演方法通过设置假设条件将舰载机模型转换成仿射形式不同,将舰载机模型转换为更一般的非仿射形式,放宽了假设条件,并在此模型基础上设计控制律方法,使高度、迎角、俯仰角和俯仰角速率等误差满足预先设定的范围。该方法减少了计算量,控制器结构更加简单,同时对舰尾流扰动具有较强的鲁棒性,提高了着舰航迹精度。

Abstract:

A new control method based on prescribed performance is proposed for non-affine model during landing, while considering the impact of the airwake disturbance. In contrast to the traditional backstepping method that the carrier model should be transformed into an affine form by setting the hypothesis condition, the proposed method transforms the carrier-based model into a more general non-affine pure feedback form and relaxes the assumptions. The proposed control scheme is capable of guaranteeing tracking errors of height, velocity, altitude, pitch angle, and pitch rate with the prescribed performance. The presented controller possesses much lower computational costs, while has strong robustness for the airwake disturbance, and improves the accuracy of the landing tracking.
