The processes which are found in various chemical industries have a complex dynamics in the sense that they are generally non linear, having dead time, inverse response and a severe multivariable interaction which makes the controlling of such processes difficult. In the present work an industrial process of first order with dead time is taken up as a case study for which controllers are designed incorporating dead time compensation and inverse response compensation techniques. The control performances of uncompensated and the compensated controllers are also compared.
