Polynomial stabilization method has important feature in PID tuning. It computationally characterizes the entire set of admissible PID gains for various control system configurations. This paper shows a correction is needed in order to find all robust PID region controllers that satisfy a given robust performance. We also provides selection procedure for searching the best PID gains controllers in the obtained PID gains region. Then, the corrected polynomial stabilization algorithm is applied on a short DC servo-driven belt conveyor system. Here, we suggest a simple model for the system. The admissible PID gains are showed both in 2D plot at specified value of k p, and in 3D plot for various values of k p. Hence, this paper provides a viable and practical means for modeling and robust PID tuning for a short DC servo-driven belt conveyor system.
