This paper describes one of the ways how to decide the initial control parameters after the analog type control system is changed to digital control system. If the old control parameters were already known, the initial control parameters for initial operation could be decided easily. But sometimes, it is very difficult for the control system developer to decide initial parameters before plant machine starts up. In that case, if there is a big difference between initial parameters and optimal parameters, the whole plant itself can be in very dangerous conditions. Here is a very simple experimental method which can be very easy but useful to engineers.
