An active energy balancing method for multiple momentum wheels of a combined spacecraft

Abstract

The present application discloses a method, apparatus, spacecraft, medium and equipment for active energy balancing of multiple momentum wheels in a combined spacecraft, which obtains the body coordinate system of each momentum wheel; obtains the moment of inertia and angular velocity of each momentum wheel; determines the corresponding energy storage coefficient and generalized energy function value based on the moment of inertia and angular velocity of each momentum wheel; calculates the sum of the generalized energy function values ​​corresponding to each momentum wheel with an energy storage coefficient greater than a preset threshold, and determines the energy balancing factor of each momentum wheel with an energy storage coefficient greater than the preset threshold based on the sum of the generalized energy function values; obtains a pre-constructed energy balance condition equation, and solves the energy balance condition equation to obtain the angular velocity solution of each energy wheel; actively controls the angular velocity of each momentum wheel based on the angular velocity solution and the energy balancing factor, so that the angular momentum of the combined spacecraft reaches energy balance, thereby solving the problem of energy balance distribution of multiple momentum wheels in the combined spacecraft under different energy levels.
