Multi-spacecraft task intelligent planning and control method for complex dynamic environment

Abstract

The invention discloses a multi-spacecraft task intelligent planning and control method for a complex dynamic environment, and the method comprises the steps: randomly generating a large amount of sample data based on a three-pulse indirect transfer model through combining with a reserved task orbit dynamic environment of a spacecraft; estimating the transfer trajectory parameter of the potentialtarget by using the neural network with complete learning and combining the actual task scene of the spacecraft, and substituting the estimated value of the neural network into the constructed task comprehensive performance evaluation model to calculate the single-satellite task performance; performing multi-spacecraft task coordination allocation by using a distributed bidding and tendering market mechanism to obtain a scheduling scheme with optimal global task efficiency; and the task spacecraft designing an accurate transfer track in a complex dynamic environment according to the task allocation result, generating a control instruction and controlling the spacecraft to complete a task. According to the method, the defects of poor planning real-time performance and low control precisionwhen an existing method is used for processing a multi-satellite task under the condition of a complex dynamic environment are overcome.
