- W3204232098 abstract "In order to realize the smooth transition from Beidou-2 system to Beidou-3 system, the orbital positions of IGSO-2 and IGSO-3 satellites will be adjusted. Multiple constraints such as control time, geographic longitude of ascending node, semi major axis, eccentricity and argument of perigee need to be considered in IGSO satellite orbital position adjustment. It takes a long time to make the strategy by trial and error method in the project, and the strategy can not achieve the minimum fuel consumption. In order to solve this problem, the IGSO satellite orbital position adjustment is decomposed into drift control and brake control. The control quantity of drift control is obtained by analytical method, and the brake control is transformed into control optimization problem with multiple constraints. A in-plane two-body motion model is established, and the constraint conditions are analyzed. The calculation method of IGSO satellite braking control strategy based on differential evolution algorithm is proposed. The objective function is established by integrating fuel consumption and constraint conditions, and the control time and speed increment of multi batch control are solved. The simulation results show that the algorithm improves the formulation time of IGSO satellite orbital position adjustment control strategy from the original hour level to the minute level, at the same time, the fuel consumption is minimized, which is conducive to extending the life of the satellite." @default.
