<p>A control method uses a controller for controlling a predetermined process parameter by a predetermined control parameter. The method comprises a step of determining an optimal control parameter value for each control step, a step of selecting a control parameter value corresponding to an actual setting condition change of the controller from the determined control parameter values, a step of changing the control parameter value set in the controller to the control parameter value selected in the selection step, and a step of output a control signal based on the changed control parameter from the controller.</p> |
