Description
technical field [0001] The invention belongs to the technical field of electromechanical control, and in particular relates to a reaction flywheel control method for improving the energy utilization rate of micro-satellites. Background technique [0002] In the engineering practice of the reaction flywheel, it is often encountered in the adjustment process of the reaction flywheel to reduce the reaction flywheel from high speed to low speed. For example, when the reaction flywheel is running at high speed, it is often necessary to unload the reaction flywheel. At present, the commonly used adjustment method of the reaction flywheel during the deceleration process is mainly to use the method of converting mechanical energy into heat energy by the energy consumption resistor to decelerate the reaction flywheel. In the application of small satellites, the problem of energy utilization is particularly prominent. This method does not make full use of the pumping characteristics o...
