An Auto-tuning Scheme of Pressure Control for PID Controllers

Abstract

In today’s modern day and age the world is moving towards automation and an increase in global competition is demanding efficient ways of process control which is an important factor for any Industry. To regulate process variables like temperature, pressure, etc. the widely used controller is the Proportional Integral Derivative (PID) Controller, but this controller comes with its own set of disadvantages namely tuning of its control parameters and thus auto-tuning can be very beneficial. The optimal method to extract the peak performance of the PID controller by tuning the parameters is still an open question. In this paper, we have worked on various approaches and used tuning methods such as Ziegler Nichols Method, Modified Ziegler Nichols Method, Internal Model Control Method, and Tyreus-Luyben Method are considered while designing the algorithm in MATLAB of the PID Controllers.
