[Abstract]:With the development of rapid response space technology, the rapid launch of remote sensing satellite and its application in emergency observation planning have put forward higher requirements. In this paper, the characteristics of mission-oriented satellite emergency observation planning are analyzed, and the load allocation method of emergency observation satellite platform and the multi-satellite cooperative planning method of emergency observation satellite are studied. The main work is as follows: 1. A mission-oriented model for emergency observation planning of remote sensing satellites is established. This paper analyzes the process and problem elements of mission-oriented emergency observation planning for remote sensing satellites, and puts forward a method for analyzing the requirements of emergency observation missions based on QFD (Quality Function Deployment) quality function expansion method. In this paper, a process model of emergency observation planning system for remote sensing satellite is constructed. The problem of emergency observation planning of remote sensing satellite is decomposed into two sub-problems, namely, self-fitting optimal configuration of emergency remote sensing satellite platform and multi-satellite cooperative planning. 2. The load assignment algorithm of satellite platform based on genetic algorithm is designed. According to the characteristics of satellite platform load configuration elements, the performance description tree of satellite platform and payload is constructed, and the satellite platform load configuration model is established to adapt to the task, aiming at the characteristics of satellite platform load optimization model. On the basis of fully considering the requirements of mission observation, the cost of satellite platform load allocation, and the resource consumption in observation process, a new method of satellite platform load allocation based on genetic algorithm is proposed. Simulation experiments are designed to verify the correctness and validity of the algorithm. 3. A multi-satellite cooperative programming algorithm based on feedback modified contract net is proposed. Based on the analysis of the characteristics of emergency Earth observation satellite cooperative mission planning, a service center-worker model multi-Agent cooperative planning architecture is constructed, and a multi-satellite cooperative planning algorithm based on feedback modified contract net is proposed. The multi-star cooperative task planning algorithm based on feedback modified contract net can not satisfy the problem that the cooperative characteristic can not be satisfied in the process of task deletion caused by conflict. In the process of winning the bid of satellite Agent, the feedback correction target is added. The feedback correction process is used to improve the degree of emergency task coordination. Experiments show that this method can effectively solve the problem of multi-satellite cooperative emergency observation of remote sensing satellites. The experiment system of multi-star cooperative planning for emergency observation of remote sensing satellite is designed and implemented. The key technologies proposed in the paper are verified to promote the transformation to practical application.
