Abstract
A characteristic change, disturbance, and an abnormal state are accurately detected with no use of a high-accuracy simulation model. A control device for controlling a control target includes a predictive value calculator that outputs a predictive value of an output value to an input value with respect to a model of the control target, a prediction error calculator that calculates a relational value indicating a relationship between the predictive value and a measured value of output of the control target; and a change detector that compares a first relational value to a second relational value, the first relational value being the relational value in a reference state in which the control target operates normally, the second relational value being the relational value in an operating state in which the control target is operated.
