Abstract
An anomaly determination apparatus determines an anomaly of a current control apparatus which supplies a control current to a control target and includes a current anomaly determination section. The current anomaly determination section is configured to compare a normal numerical range within which a state quantity changing with the control current falls in a particular state with a particular state quantity which is the state quantity corresponding to the control current generated by the control current generation section in the particular state, and determine that at least one of the reference resistor, the reference current generation section, and the control current generation section is in an anomalous state in the case where the particular state quantity has deviated from the normal numerical range. By using the current anomaly determination section, the anomaly determination apparatus can determine an anomaly of the current control apparatus.
