In the last five decades (from 1957) several modifications have been made on the smith predictor structures to improve the servo and regulatory responses. In this paper, we have made an attempt to give an overall idea of controller design for unstable processes. We had cited more than sixty papers on unstable and time-delayed processes. From the analysis we learned how to tune the controller based on time domain analysis and frequency domain analysis. We had made the simulation work for some of the papers mentioned here and still we are working on how to improve the performance of the process variable and manipulated variable. At last, we also suggested how to tune the controller by using optimization techniques using robust controller.
