Abstract

Abstract: This research focus on controlling Multiple Input Multiple Output (MIMO) process for Reflux (L) – Boil up rate (V) configurations. There are a total of 3 phases in the simulation process. In phase 1, transfer functions and best fit curves are obtained for LV. The best fits are 88.28 % (CV1) and 93.07 % (CV2). The controller for LV configurations was developed. In phase 2, the controllers were tuned and analyze based on the set point tracking and disturbance rejection. In phase 3, partial decouplers were developed and analyzed for a static plus dynamic approach. It is observed that the partial decoupler provides better performance as compared to conventional full decoupler. The performance was proven based on the outcomes from the simulations and calculations. As a conclusion, the partial decoupler is able to minimize the loops interaction and obtain the best set point tracking and disturbance rejection.
