AI Technical Summary

Technical Problem

Existing UAV trajectory optimization techniques ignore the underactuated characteristics of rotorcraft UAVs and the strong coupling of antenna attitude, resulting in model mismatch, wasted attitude degrees of freedom, and physical infeasibility, which affects communication performance.

Method used

A discretized spatiotemporal model of an UAV air-to-ground communication system is constructed. Combining a dual-loop control architecture and rigid body dynamics principles, the coupling relationship between the UAV's flight dynamics and the communication antenna is optimized. The trajectory is optimized using sequential convex approximation and semi-definite relaxation algorithms, and the attitude control antenna beam is actively utilized.

Benefits of technology

This approach achieves tight coupling between UAV flight dynamics and communication antennas, improving the transmission rate and coverage performance of the communication system, avoiding the mismatch between theory and practice, and providing an efficient optimization solution.

Abstract

本发明公开了一种四旋翼无人机通控一体轨迹设计框架和优化方法,属于无线通信与无人机控制交叉技术领域。该方法首先构建无人机离散化时空模型,基于双环控制架构与微分平坦特性,建立天线姿态向量与无人机推力向量及重力向量之间的显式动力学耦合约束,基于水平‑水平天线配置构建受空间位置与瞬时姿态共同影响的通信增益模型;建立以最大化平均通信速率为目标的轨迹优化问题,并利用序贯凸逼近SCA与半定松弛SDR算法,通过矩阵提升技术将非凸的刚体耦合约束转化为凸的线性矩阵不等式进行迭代求解。本发明实现飞行动力学与通信天线姿态的深度协同,能够利用飞行姿态调整实现天线波束对准,在保证轨迹物理可执行性的同时显著提升通信质量。
