The present invention relates to a program and device for testing a proportional-integral-differential (PID) controller. A program for testing a PID controller comprises the steps of: (a) receiving information of a PID controller; (b) setting a control variable for a proportional gain, differential gain or integral gain of a signal input to the PID controller; (c) setting an input indication value corresponding to the signal input to the PID controller; and (d) determining whether the PID controller is satisfactory by checking PID control for the input indication value of the control variable. According to the present invention, there arises an advantage of checking the control characteristics of a PID controller without connection to a plurality of measuring devices. |
