Design and Simulation of Generalized Analytical Predictor with Adaptation Filter for an SOPDT MIMO System

This paper deals with the control of a multi-input, multi-output chemical process that involves significant time delay using Generalized Analytical Predictor. The Generalized Analytical Predictor (GAP) provides a truly generalized approach to dead time compensations and significant improvement has been achieved in the regulatory response as compared to the Internal Model Control (IMC). An adaptation filter based approach is applied to a higher order distillation column model and an improved performance is obtained with GAP compared to IMC.
