Abstract

This provides an anomaly detection method to ensure reliable equipment protection. [Solution] The abnormality determination device comprises a command unit that outputs a control command value to a device to be controlled, an acquisition unit that acquires an operating status value from the device to be controlled, and an abnormality determination unit that determines an abnormality if the deviation between the output control command value and the acquired operating status value deviates by a predetermined threshold or more and continues for a predetermined waiting time or longer. The abnormality determination unit determines the abnormality based on the deviation between the control command value and the control command value from the past for a predetermined delay time.
