Abstract

The invention provides a control digital system for a high-reliability energy storage flywheel dragging motor, which is used for controlling a driving motor of a magnetic suspension energy storage flywheel. The control digital system mainly comprises an interface circuit, a digital signal processor (DSP) control central pivot, a motor driving power amplification module, a magnetic suspension energy storage flywheel dragging motor body and a sensor circuit, wherein the DSP controller acquires data such as a dragging motor rotate speed signal, motor winding current and the like by the sensor interface circuit; and the control system regulates the running state of the motor according to a position signal and a speed signal, received by a sensor, of a motor rotor and a current signal of a dragging motor winding coil. In the invention, the integration design of a dragging motor digital controller of the magnetic suspension energy storage flywheel system is realized, so that the stability and integration level of the controller of the magnetic suspension energy storage flywheel dragging motor are improved greatly, and the high-precision control of flywheel motor dragging is completed only by using one on-chip system-level DSP chip.
