This paper presents design of a PID controller for the system of a pump-controlled motor with a long transmission line. By using possibilities offered by computers and software the graphical method is used in the design of PID controllers. The D–decomposition method including system performances, damping and settling time was applied. This type of controllers frequently satisfies practical needs because the feedback loop system is fast, and the static error is reduced to 0. The proposed method allows easy design of PID controllers in significant modifications of lengths of the transmission line. The system performances are included in a new manner without the need for calculation of Chebyshev functions for every change of the damping coefficient thanks to strong software support.
