This paper deals with the control of temperature of distillation column. This distillation column is very difficult to control because operational conditions are changed day by day. Dynamical models are built from operational data with ARMAX model. The generalized predictive control (GPC) method is very effective to control temperature in this system. The control derived this method is applied to estimate PID control equivalently. Control results are excellent and will be applicable for practical plant.
