Abstract
The present invention includes a main control system driving an exciting coil of a component to be driven. The invention also includes a sub-control system that backs up the main control system when the main control system fails. The sub-control system and the main control system both have a self-diagnostic capability and the sub-control system is diagnosed for failure prior to the main control system, so that the availability of the back up system is determined before the main control system is activated.
