Population Game Based Distributed Allocation Method for Spacecraft Attitude Control
For the attitude control of combined satellites composed of multiple cellsats,a two-layer attitude control method including control torque calculation layer and redundant torque distribution layer is designed.The problem of redundant torque distribution is transformed into the strategy selection problem of population game.By setting a benefit function that comprehensively considers energy consumption,flywheel output torque margin and flywheel angular momentum margin,the population game model is established with torque distribution coefficient as the group mass and cell satellite as the strategy.Considering the different evolution strategies formed by imitation and comparison in group evolution,the Nash equilibrium of the game is solved by using group dynamics,and the distributed redundant torque distribution method is formed by using the group game theory with limited strategies.Finally,the effectiveness of this allocation method is verified by simulation experiments.
