Collaborative autonomous task planning of multiple unmanned aerial vehicles(UAVs)is expected to significantly enhance task perception efficiency and execution performance.In this paper,an overview of the key technologies in collaborative autonomous task planning systems of multiple UAVs is presented,including knowledge representation methods,the integrated sensing and communication technology,and the task scheduling and trajectory planning technology of the UAVs.Regarding knowledge representation methods,a context-aware knowledge base construction method is proposed,and a multi-domain fusion knowledge graph and dynamic knowledge graph updating and sharing methods are summarized.For the integrated sensing and communication technology in multi-UAV collaborative task execution scenarios,an environment-adaptive and flexible scalable multi-UAV collaborative sensing and communication integration framework is proposed,the theoretical performance limitations of collaborative sensing and communication integration are analyzed,and resource sharing methods tailored to varying task demands are presented.Regarding the task scheduling and trajectory planning problem in multi-UAV collaborative task execution scenarios,a resource-adaptive multi-UAV collaborative autonomous task scheduling scheme is presented,then a dynamic model-based multi-UAV collaborative autonomous trajectory control strategy is discussed.Finally,a robust control mechanism in imperfect multi-UAV collaborative environment is proposed.
