The processes which contain at least one pole at the origin are known as integrating
systems. The process output varies continuously with time at certain speed when they are …

abstract PID controllers are still widely practiced in the industrial systems. In the literature,
many publications can be found considering PID controller design for unstable processes …

In this paper, a new concept on PI design for time delay systems is introduced. The concept
is weighted geometrical center of the stabilizing controller parameters region. Calculating of …

This study proposes an analytical design method of fractional order proportional integral
(FOPI) controllers for first order plus time delay (FOPTD) systems. Suggested technique …

In this paper, a practical PI‐PD controller parameter tuning method is proposed, which uses
the incenter of the triangle and the Fermat point of the convex polygon to optimize the PI‐PD …

This paper aims to put forward an analytical solution for tuning parameters of a fractional
order PI (FOPI) controller for stable, unstable, and integrating processes with time delay …

The simplicity of the proportional-integral controller makes it very popular in many practical
engineering applications. In the literature, several approaches have been introduced for …

Purpose: The aim of this study is to design FO-PI controller for time delay systems using the
centroid of the convex stability region method based on the stability boundary locus. The …

In this study, the effectiveness a PID controller designed through weighted geometric center
(WGC) method is investigated in order to actively attenuate the free and the forced vibrations …

This paper presents an application of the d-decomposition technique to the design of the
control structure for a two-mass drive system. In the paper the main control approaches for …
