AI Technical Summary

Technical Problem

Tail-mounted vertical take-off and landing (VTOL) drones face significant challenges in attitude control during the hovering phase. Existing controllers do not consider input constraints, resulting in limited or unstable control performance. Furthermore, the safety of PID parameter tuning is difficult to guarantee, and the drones are prone to instability, especially during maneuvers.

Method used

The ADRC control method based on quaternion attitude error is adopted. By recalculating the total attitude error, a tracking differentiator and a disturbance observer are introduced to design a disturbance compensation mechanism, limit the yaw attitude error, and perform motor thrust control allocation.

Benefits of technology

Stable attitude control of UAVs during the hovering phase was achieved, eliminating the singularity of Euler angle attitude control, balancing speed and overshoot, improving the transient and steady-state performance of the control system, and reducing the safety risks of PID parameter tuning.

Abstract

本发明涉及无人机控制技术领域,具体提供了一种基于四元数姿态误差的ADRC尾座式无人机悬停控制方法,包括如下步骤:S1:将姿态误差分为倾斜误差和偏航误差,并对偏航误差进行限制,以得到新的总姿态误差,并通过跟踪微分器对新的总姿态误差的波形进行输入整形;S2:基于新的总姿态误差,建立开环被控系统;S3:设计扰动观测器及ADRC控制器;S4:计算无人机中每个电机的期望推力并进行控制分配。本发明可消除尾座式垂直起降无人机中PID参数调试的安全隐患,具有良好的暂态性能和稳态性能,可以兼顾快速性与超调量,可达到较好的跟踪效果。
