PROBLEM TO BE SOLVED: To provide a direct type process simulater application and control device and a method, by which a model prediction control is constructed by directly using a process simulater. SOLUTION: The device and method are provided with a sensor for measuring the disturbance of a process and the observation output of the process, a means for storing these respective measured values and a process manipulated variable command value, a means for predicting the disturbance of the process from a present time point to a prescribed point in the future, a means for predicting the action of a process controlled variable from the measured values, the process manipulated variable command value and the predictive value of the disturbance of the process, a means for storing a step response time sequence over a prescribed period at each of predetermined operating points, a means for selecting a present step response time sequence out of step response time sequences for each of operating points corresponding to the process manipulated variable command value and the measured value of the disturbance of the process, and a means for determining an optimal manipulated variable command value for a prescribed period by inputting the predicted process value and the selected step response time sequence at least.
