基于当前迭代反馈点到点迭代学习控制的航空器4D航迹跟踪控制
4D Trajectory Tracking Control for Aircraft Based on Point-to-Point Iterative Learning Control with Current-Cycle Feedback
摘要
Abstract
A point-to-point iterative learning control method with the current-cycle feedback is proposed to enable aircraft to achieve an accurate four-dimensional(4D)trajectory tracking.To this end,the 4D trajectory tracking control problem is formulated into a point-to-point tracking control issue with an external disturbance.Then,the optimal point-to-point iterative learning control law is derived based on the successive projection method.Further,the current-cycle feedback error is added to the control law,so that the tracking error is reduced in both time and iteration domains.Finally,a numerical simulation is carried out using the kinematic model of an unmanned aerial vehicle and 4D trajectory data.Obtained results demonstrate that the proposed method can quickly reduce the trajectory tracking error even in the presence of gust interferences.Compared with the commonly used average velocity method and the velocity correction method,the proposed method makes full use of the past and current running data,and can continuously improve the accuracy of 4D trajectory tracking with the repetitive operation of aircraft between city pairs.关键词
