无人机纵向飞行控制器的FLNN轨迹线性化设计

摘要

A new control method combining Functional Link Neural Network (FLNN) and Trajectory Linearization Control (TLC) was proposed, which was then used in the design of a UAV longitudinal flight controller. The design process of the controller was introduced in detail, and a simulation was made using the new control scheme, which was compared with TLC controller. The results showed that the proposed control program can effectively reduce the impact of modeling error and external disturbance on the controller and improve the robustness of the system.%提出一种将函数连接神经网络(FLNN)和轨迹线性化方法(TLC)相结合的新的研究控制方法,并采用此方法设计了无人机纵向飞行控制器.介绍了采用此方法设计无人机纵向飞行控制器的过程,并利用新控制方案对控制器进行了仿真验证,且与TLC控制器进行了比较.结果表明所提出的控制方案可有效地降低建模误差和外部干扰对控制器的影响,提高系统的鲁棒性.
