Performance Evaluation of Various Controllers Designed for an Industrial First Order plus Delay Process

Saurabh Rajvanshi , Pradeep Juneja

As most of the industrial processes can be modeled using first order plus dead time model. A blending process, which can be represented as a FOPDT model, is selected for controller design based on different well established and relatively newer controller tuning methods. Based on comparison of set point tracking capability of the controller and dynamic and steady state characteristics, best controller tuning technique is determined for the process.
