摘要
Abstract
Nowadays most advanced GEO satellites collocate electric thrusters with high specific impulse to execute north-south stationkeeping, which can efficiently decrease propellant consumption. For GEO satellites, electric thrusters usually controls nothing but inclination,whi le bipropellant thruster controls eccentricity and mean longitude.Aiming at the stationkeeping of GEO satellite with electric thruster,a sort of combination control method of inclination and eccentricity using electric thrusters was proposed.The optimization model for solving the control equations was developed. Two kinds of simplified algorithm were induced by reducing the optimization model dimensionality, which deeply decrease the computational complexity and was convenient for autonomous computation of GEO satellite stationkeeping.This method can be used to simulate the combined inclination and eccentricity simultaneously and precisely, which leads to the reduction of propellant consumption for stationkeeping.The simulation results indicate that the combination control method has the advantages of high stationkeeping efficiency and high control precision.关键词
