Abstract
Most of the chemical processes are multivariable in nature. Control of multivariable industrial processes becomes a challenge due to the inherent interactions among variables, modelling uncertainty and various disturbances. The objective of this paper is to design a PI controller for CSTR process with decoupler to meet the desired transient response specifications. Stability of the proposed system is tested using simulation results. Also the performance indices are compared for designed controller for a change in reactor dynamics. A good performance of set point tracking and disturbance rejection is obtained for the decoupled process.
