| Abstract: | This paper is suggesting a practical method for realizing optimal digital compensation of process control systems. Initially, a cascade continuous compensator prototype is designed and further it is converted into its digital equivalent. The purpose of the compensator is to eliminate some properly selected poles of the original control system transfer function, to introduce new dominant poles and specific system amplification. As a result, the system's transient response and stability are considerably improved. The control system’s relative damping ratio, percent maximum overshoot, phase margin, rise and settling times, are optimized.
