All chemical processes in process industries usually have two or more controlled outputs requiring two or more manipulated variables generally called Multi Input Multi Output (MIMO) process. In this paper an attempt is made to review the practical difficulty in applying control strategies for a multivariable process. The control strategies considered here are multi-loop PID control, multi-loop IMC-PID control and multi loop H∞-PID control. These strategies are reviewed by applying them to the quadruple tank process which is the bench mark multivariable process.

Abstract


All chemical processes in process industries usually have two or more controlled outputs requiring two or more manipulated variables generally called Multi Input Multi Output (MIMO) process. In this paper an attempt is made to review the practical difficulty in applying control strategies for a multivariable process. The control strategies considered here are multi-loop PID control, multi-loop IMC-PID control and multi loop H∞-PID control. These strategies are reviewed by applying them to the quadruple tank process which is the bench mark multivariable process.
