Damping of Surge Effects and Enhancement of Dynamic Response of Distillation Plant Using MIMO Fuzzy Control

摘要

Distillation process is a controlled process that must be done at maximum efficiency and with the highest quality. In this work, due to complexity and non-linearity of the process, the distillation plant and the intelligent fuzzy controller, which is used for damping the surges and enhance the process, are simulated in MATLAB, A new design of fuzzy control for separator is introduced. The design based on the utilization of linear state-estimation to generate the internal knowledge-base that stores input-output pairs. This collection of pairs is then used to build a feedback MIMO fuzzy controller. The proposed closed-loop fuzzy control system maintains the system asymptotically-stability while it enhances the system time response and reduce the effect of surges to achieve better control of the concentration of tower. Simulation studies are carried out to illustrate the tower performance using the proposed controller.
