Abstract

An integrated magnetic suspension flywheel magnetic bearing digital control device includes an interface circuit, an A / D conversion chip, a FPGA module and a DSP module. The device obtains data of the magnetic bearing rotor displacement signals, circuit of the coil and rotating velocity, the DSP module generates a control volume in terms of a control algorithm and delivers it to the FPGA, which carries out PWM modulation based on the control volume and current signals to transfer its signal to a full-bridge energy conversion circuit to generate control current needed by the magnetic bearing coils to realize the active control to magnetic suspension flywheel magnetic bearing system.

Description

Technical field [0001] The invention relates to a high-performance, integrated magnetic bearing digital control device for a magnetic levitation flywheel, which is used for high-precision control of the magnetic bearing system of a magnetic levitation flywheel, and is especially suitable for applications such as high performance and high integration. The control device is also suitable for Control of other magnetic bearing systems using full bridge power conversion modules. Background technique [0002] The flywheel is the basic attitude control actuator on small and medium-sized satellites. Compared with the traditional mechanical bearing flywheel, the maglev flywheel has the advantage of active vibration control, so it has broad application prospects in high-precision satellites. In addition, the magnetic bearing has no friction, which avoids the wear of the mechanical bearing itself due to friction. Its reliability depends on the reliability of the electronic components o...
