Integrated magnetic suspension flywheel digital control device with high reliability

Abstract

The invention provides an integrated magnetic suspension flywheel digital control device with high reliability, which is used for controlling a motor and an electromagnetic bearing of a magnetic suspension flywheel system, and mainly comprises an interface circuit, a field programmable gate array (FPGA) system, a magnetic bearing control power module, a motor control power module, a magnetic suspension flywheel system and a sensor circuit, wherein the FPGA system acquires data, such as the displacement signal of the magnetic bearing rotor, a revolving speed signal, magnetic bearing coil current, motor winding current and the like by the interface circuit. On the one hand, the PFGA system performs active control on the electromagnetic bearing in accordance with the displacement signal of the magnetic bearing rotor, the magnetic bearing coil current and the revolving speed signal; on the other hand, the FPGA system controls flywheel output torque in accordance with an output torque instruction, the motor winding current and the revolving speed signal. The device in the invention is used for realizing an integration design on the magnetic bearing digital controller and the motor digital controller, thus greatly improving the integrated level of the magnetic suspension flywheel system, reducing volume and weight, lowering the power consumption of the controllers and improving the reliability of the controllers.
