Abstract
In an apparatus for detecting an abnormality of a control system, the internal property calculating section thereof calculates an internal property of the control system only on the basis of a command value representing a position or a speed of the control system, and the abnormality judging section judges the existence of abnormalities of the control system on the basis of an internal property calculated by the internal property calculating section and an actual internal property of the control system. Consequently, the apparatus can precisely detect abnormalities without being influenced by an observed noise or an operational error.
