AI Technical Summary

Technical Problem

Existing technologies struggle to achieve stable, accurate, and safe flight of drones under tunnel ventilation conditions, especially in environments with strong wind disturbances. Traditional methods suffer from problems such as complex models, high computational load, response lag, and significant chattering.

Method used

A nonlinear dynamic model of a UAV under tunnel wind field is constructed. Multi-source data fusion is performed by combining ultra-wideband wireless communication, lidar and visual sensors. The position and attitude information of the UAV is output by using an extended Kalman filter. A disturbance predictor based on the tunnel fluid dynamics model is introduced. The desired attitude command and control torque are generated by inner and outer loop controllers to achieve feedforward compensation.

Benefits of technology

It significantly improves the anti-disturbance capability of UAVs in strong through-flow and turbulent environments, ensures the rapid response and robustness of the system, avoids the risk of collision or loss of control, and achieves high-precision flight control.

Abstract

本发明涉及无人机飞行控制技术领域,公开了一种隧道贯通风场下无人机抗扰动飞行控制方法,该方法包括:构建无人机在隧道风场作用下的非线性动力学模型;利用扩展卡尔曼滤波器对多源数据进行融合;扰动预测器根据无人机的位置与姿态信息预测未来时间段的扰动趋势值,将扰动趋势值作为前馈补偿量注入外环位置控制器及内环姿态控制器;外环位置控制器生成期望姿态指令和总升力指令;内环姿态控制器基于外环位置控制器输出的期望姿态指令及内环有限时间扩张状态观测器提供的姿态扰动估计,计算滚转控制力矩、俯仰控制力矩及偏航控制力矩。本发明基于流体力学模型的前馈预测机制赋予其前瞻性抗扰能力,克服了传统反馈控制的滞后性。
