Set Point Tracking Capability Analysis of Various Controllers Designed For a First Order plus Dead Time Process

Abstract

It is very common to find an industrial process that can be modelled using first order plus dead time (FOPDT) model such as, a blending process. This process is selected for controller design based on different well established and relatively newer controller tuning methods and compared for set point tracking capability of the controllers. Based on comparisons of set point tracking capability of the controller and dynamic and steady state characteristics of step responses, best controller tuning technique is determined for the selected process.
