面向植保任务的无人机集群系统及其应用研究

摘 要

随着无线通信技术的发展，无人机在民用和军事上的应用越来越广泛。由于单无人机负重少、体积小、覆盖面积小，不能满足复杂任务需求，近年来，关于无人机集群协同编队控制方面的研究发展迅速。植保无人机在实际作业过程中，若作业区域面积较大，单次植保作业无法满足作业要求，需要中途多次返航至补给点进行药剂装填或电池更换等补给作业。这就要求对无人机的作业路线进行合理规划，从而达到提高作业效率的目的。随着中国城镇化率的进一步提高，对于转变农业发展方式，支撑现代农业发展，增强农业综合生产能力，发展高作业效率的农机装备是大势所趋。若仅采用１架植保无人机进行作业，作业总时间较长，效率有限。针对这种情况，本文基于改进粒子群算法，提出了一种多植保无人机协同路径规划解决方案，采用多架无人机协同作业，提高劳动效率。

基于无人机集群协同编队控制应用广泛，比如无人机集群、无人机巡警等行业，都会运用到基于集群协同编队控制方法的无人机系统。更高效率和更高精度的无人机集群协同编队控制系统一直是研究的热点。在我们日常生活中，无人机集群协同编队控制系统随处可见，因为其相比其他的控制方式而言，运行稳定且控制精度较高等优势，最重要的是无人机集群协同编队控制系统在集群演示等方面具有很好的优势。随着自动控制技术和微电子技术的不断革新，目前的技术水平为实现无人机集群协同编队控制系统打下坚实的基础，提供扎实的理论依据。

本次设计主要以无人机集群协同编队控制系统设计应用作为研究背景，运用MATLAB仿真工具搭建相应的仿真模型。该模型利用MATLAB软件中的模块库，建立了无人机集群协同编队控制系统在无人机系统应用中的系统仿真模型，通过 MATLAB仿真软件搭建仿真模型,运行仿真，并对无人机集群协同编队控制系统的仿真结果进行了分析。利用MATLAB软件Simulink工具箱中模块针对无人机集群协同编队控制系统技术搭建了仿真模型。最后针对实例进行仿真验证，理论计算值和仿真结果的一致性证明了所搭建仿真模型的正确性，从而为同行从业人员或学习者提供可靠的参照。

Abstract

With the development of wireless communication technology, uav is widely used in civil and military fields. Due to the small weight, small volume and small coverage area of single UAV, it cannot meet the requirements of complex tasks. In recent years, the research on cooperative formation control of UAV cluster has developed rapidly. In the actual operation process, if the operation area of plant protection UAV is large, a single plant protection operation cannot meet the operation requirements, and it is necessary to return to the supply point for replenishment operations such as drug loading or battery replacement. This requires reasonable planning of uav operation route, so as to achieve the purpose of improving operation efficiency. With the further improvement of China's urbanization rate, it is the general trend to change the way of agricultural development, support the development of modern agriculture, enhance the comprehensive agricultural production capacity, and develop agricultural machinery and equipment with high operational efficiency. If only one plant protection UAV is used for operation, the total operation time will be long and the efficiency is limited. In view of this situation, this paper proposed a cooperative path planning solution of multiple plant protection UAVs based on improved particle swarm optimization algorithm. Multiple UAVs were adopted to work cooperatively to improve labor efficiency.

Uav cooperative formation control based on uav cluster has been widely applied, such as UAV cluster, UAV patrol and other industries, will be used in uav system based on uav cooperative formation control method. Higher efficiency and higher precision uav cooperative formation control system is always a research hotspot. In our daily life, the uav cooperative formation control system can be seen everywhere, because compared with other control methods, it has the advantages of stable operation and higher control accuracy. The most important is that the UAV cooperative formation control system has good advantages in cluster demonstration and other aspects. With the continuous innovation of automatic control technology and microelectronics technology, the current technical level has laid a solid foundation and provided a solid theoretical basis for the realization of uav cluster cooperative formation control system.

This design is mainly based on the uav cluster cooperative formation control system design and application as the research background, using MATLAB simulation tools to build the corresponding simulation model. In this model, the module library of MATLAB software is used to establish the system simulation model of UAV cluster cooperative formation control system in the application of UAV system. The simulation model is built and run by MATLAB simulation software, and the simulation results of UAV cluster cooperative formation control system are analyzed. The simulation model of uav cluster cooperative formation control system is built by using the module in MATLAB Simulink toolbox. Finally, the consistency of theoretical calculation and simulation results proves the correctness of the simulation model, so as to provide reliable reference for practitioners or learners in the same field.
