特征结构配置法在无人机控制系统中的应用

Application of Eigenstructure Assignment in UAV Control System

特征结构配置可通过分析系统的模态,得到系统特征结构与时域响应之间的关系,设计出结构简单、鲁棒性强的控制器。应用输出反馈特征结构配置设计了无人机控制律,仿真结果表明,无人机的纵向运动和横侧向运动具有较好的飞行动态性能,实现了无人机纵向通道和横侧向通道的内部解耦。

Through analysis of system modality, eigenstructure assignment can obtain the relationship between the system eigenstructure and time domain response, so that the controller with simple structure and better robustness can be designed. UAV control law is designed by application of output feedback eigenstructure assignment. The result of simulation shows the longitudinal and lateral movement of UAV possesses good flight dynamic performance, which realizes the internal decoupling of UAV longitudinal channel and lateral channel.
