DYNAMIC TORQUE CONTROL METHOD FOR ENGINE FLYWHEEL

摘要

FIELD: electricity.SUBSTANCE: invention is related to the field of electric engineering and may be used in spacecraft angular position control systems for the orbital coordinate system. In the dynamic torque control method for the engine flywheel based on a precision frequency-phase system of speed regulation for a brushless DC motor the reference digital model of the engine flywheel is used as the source of the preset phase and frequency and the second auxiliary circuit that performs function of initial synchronisation for the model integrators with actual output coordinates of the engine. Switching from the main circuit to the auxiliary one and back is made by the circuit switch against signals at the output of a frequency-phase discriminator. The circuit switch allows functioning of the device in a control mode both for an electromagnetic and dynamic torque. Current of the engine is generated on the basis of a dynamic torque control signal and a phase mismatch signal between the output signals for the reference digital model and signals of the rotor position sensor.EFFECT: provision of the dynamic torque control for the engine flywheel with high accuracy from zero up to the maximum value within the whole range of the operating speed for the flywheel rotation.2 dwg
