  "textContent": "The invention relates to a control device of an engine, calculating a control signal (Svb) to be supplied to a controlled object (60V) for controlling the controlled amount to a target controlled amount and when a history of a change of the controlled amount does not correspond to a predetermined history, supplies the control signal to the controlled object and on the other hand, when the history of the change of the controlled amount corresponds to the predetermined history, the device corrects the control signal and then, supplies the corrected control signal to the controlled object. According to the invention, a model constructed on the basis of the Prisach distribution function is prepared as a model relating to the controlled object for calculating a correction coefficient (Khid, Khdi) for correcting the control signal such that the hysteresis of the controlled object decreases, the correction of the control signal is accomplished by correcting the control signal by the correction coefficient calculated by the model, a parameter of the model is identified on the basis of the change amount of the activation condition of the controlled object during the change of the activation condition of the controlled object and the parameter of the model is corrected on the basis of the identified parameter.",
