In this study, proportional-integral (PI) controller design with a geometric approach for first
order time-delayed systems is presented. This method can be expressed as an improved …

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 …

Control system design is a challenging task for practicing engineers. It requires knowledge
of different engineering fields, a good understanding of technical specifications and good …

In this paper, a simple PI tuning method for time delay systems is proposed. The main
characterization of the method is first to obtain the stability region in the (kp, ki)-plane using …

Most processes are nonlinear, and their control is a difficult yet important problem. The heat
exchanger is an example onesuch nonlinear process. In the present paper, the effect of …
