Analysis and Process for Uninteresting Time Compensators with Smith Predictor and Virtual Sensor

Abstract

Dead time is often present in control systems as computational or informational delay but in most cases it is very small and is neglected. Dead time is widely found in the process industries when transporting materials or energy. Generally stable processes are represented by first-order-plus-dead-time or second order- plus-dead-time models for analysis. In this paper analysis of secure processes with dead time is done. Here PI controller and Smith Predictor & virtual sensor are used as dead time compensators but virtual sensor eliminates the technology-related dead-time and makes the control of dead-time processes possible without high development costs and at the end of paper we will be compare the effectiveness of both.
