本文提出了一种复合路径跟踪控制器,使小型固定翼无人机能够跟踪预定的路径,假设飞行器配备了自动驾驶仪,高度和空速保持良好,控制器的设计采用分层控制结构。内环控制器的设计基于自抗扰控制的概念,它将响应于期望的滚转角指令,外环控制器的核心部分是基于李雅普诺夫稳定性定理设计的,以产生期望的直线路径的航向速率。倾斜转弯机动用于将所需航向速率转换为所需滚转角指令。在X-Plane模拟器上进行了半实物仿真,并进行了实际飞行试验,验证了该方法的有效性。
This article proposes a composite path following controller that allows the small fixed-wing unmanned aerial vehicle to follow a predefined path. Assuming that the vehicle is equipped with an autopilot for altitude and airspeed maintained well, the controller design adopts the hierarchical control structure. With the inner-loop controller design based on the notion of active disturbance rejection control which will respond to the desired roll angle command, the core part of the outer-loop controller is designed based on Lyapunov stability theorem to generate the desired course rate for the straight-line paths. The bank to turn maneuver is used to transform the desired course rate to the desired roll angle command. Both the hardware-in-the-loop simulation in the X-Plane simulator and actual experimental flight tests have been successfully achieved, which verified the effectiveness of the proposed method.
