ABSTRACT:
A plant model expressing an object to be controlled by a discrete mathematical model is used. Parameters of the plant model are identified in such a way as to bring an identification error, which is an error between a plant model output of an output when an input to an object to be controlled is applied to the plant model and an actual output of the object to be controlled, close to zero. By discretizing the plant model in the form of including information of part of time delay of the object to be controlled in model parameters, the information of part of time delay included in the discrete model parameters can be estimated and time delay is estimated on the basis of a change in estimated values in such a way as to be brought close to actual time delay of the object to be controlled.
