System for restoring controlled unit from abnormal condition

摘要

In a system for restoring a controlled unit from an abnormal condition, a plurality of predicted abnormal conditions and corresponding restoring procedures are prestored. When an actually generated abnormal condition matches with one of the prestored abnormal conditions, the system restores the controlled unit from the abnormal condition based on the prestored restoring procedure corresponding to the abnormal condition which matches with the actually generated abnormal condition.
