ABSTRACT:
In a method of adjusting a process control device wherein a closed loop system comprising a control subject and external compensator is approximated by a transfer function expressed by the time constant of a first-order delay filter and a dead time, adjustment is effected by displaying the step response of the closed loop system as a first response, displaying the step response of a model transfer function of the closed loop system as a second response in superimposed fashion with the first response, adjusting the respective parameters so that the difference of the first response and the second response is within a prescribed evaluation standard range, and performing prescribed conversion and setting of this model parameter as a control parameter of the controller, so that the response of the process control device is within a prescribed evaluation standard range.
