This paper presents a symbolic PI tuning method for first orders systems with time delay based on Pade approximation. The presented method is very easy to use like well-known methods such as Ziegler-Nichols and Cohen-Coon. Besides its easiness, the method performs a faster step response and no overshoot. Furthermore, it provides a good robust performance.
