Layered decision based energy consumption optimization method for communication and sensing of payload-constrained unmanned aerial vehicles

Abstract

The application discloses a kind of based on layered decision's heavy load restricted unmanned plane communication perception energy consumption optimization method, comprising: constructing unmanned plane grouping distribution system;Communication model, user satisfaction model, grouping distribution sequence model and energy consumption model are constructed, and optimization target of minimum flight energy consumption is established;In upper layer decision, distribution grouping and access sequence optimization problem is modeled as vehicle routing problem with time window, adaptive large neighborhood search algorithm is used to solve, and global distribution sequence is obtained;In lower layer decision, trajectory planning problem is modeled as Markov decision process, and deep reinforcement learning algorithm is used to solve, and flight strategy network model is obtained;Global distribution sequence and flight strategy network model are deployed to unmanned plane on-board computing unit, flight direction decision is generated according to environmental information;Output optimal distribution scheme.The application satisfies load, user satisfaction and communication reliability, and reduces flight energy consumption.
