The article presents a design and implementation of decentralized Proportional Integral (PI) controller with decoupler based on Smith Predictor for a Batch Distillation Column. Decoupler is used to minimize the interaction combining it with decentralized control algorithm. To minimize the loop interaction between the loops, an ideal decoupling technique is implemented on a First Order Plus Dead Time (FOPDT) model. The PI controller is designed using Smith Predictor method. The simulation of Smith Predictor technique has been adopted to study the main effect and the interaction effect of the Batch Distillation Column. The controller is designed and implemented on a Batch Distillation Column.
