Title:
DIGITAL CONTROL METHOD AND DEVICE OF MAGNETIC BEARING SPINDLE
Document Type and Number:
Japanese Patent JPH1082420
Kind Code:
A
Abstract:
To improve a control performance by reducing the number of A/D converters, reducing a conversion speed and increasing a sampling frequency.
The sensor output of the axis of 1-5 channels is given to MPU6 and a control calculation is carried out after being inputted to a multiplexer 12 and selected in a time sharing and converted to a digital signal by the A/D convertor 13 and the control signal is converted to an analogue signal by D/A convertors 7-11 per each axis and A/D conversion and control calculation and D/A conversion are processed sequentially.
