Abstract

Process industry many time used second order plus dead time process as an industrial process. Time taken between input and output of a phenomena in an industry is called dead time also known as transportation lag. Smith predictor is a dead time compensation technique which is used to compensate dead time. Smith predictor compare process model and actual process of the system until error between them zero, but there are some limitations of smith predictor if actual process and process model is not match. Modified Smith predictor is used to achieve stability and zero steady state error to step load response.
