Performance Analysis of Controllers Designed For Delayed Industrial Process

Abstract

In a process industry, many processes can be modelled by integral plus dead time model. In present analysis, dead time is approximated by using Taylor?s, Pade first order & Pade second order approximation techniques for an integral plus dead time model. Controller has been designed using various tuning techniques for the dead time approximated models and the performance of these controllers is compared for their set point tracking capability.
