Description

technical field [0001] The invention relates to an energy storage flywheel magnetic bearing control system based on DSP and FPGA. Background technique [0002] Energy storage flywheel is a kind of advanced mechanical energy storage device, which has the advantages of high efficiency, high energy storage density, green environmental protection, long service life, rapid charge and discharge, etc. It is a key equipment in new energy and a hot spot in international power electronics research. At present, the control system of the energy storage flywheel mainly uses a single microprocessor chip (such as a DSP chip) and a control drive circuit for control. The biggest advantage of this control scheme is that the control system circuit is relatively simple, but the biggest disadvantage of this scheme is that the degree of automatic control of the system is not high and the online real-time monitoring of the operating status of the magnetic bearing cannot be performed.
