Implementation of Plant-Wide PI-Fuzzy Controller in Tennessee Eastman Process

In the process industry, an automation system in the form of a control system is needed. The control strategy that is generally implemented in the process industry is also well-known with the plant-wide control system. The control system in the process industry uses certain algorithms installed in each process industry operating unit. In this study, one of the advanced control algorithms called with PI-Fuzzy controller is implemented and evaluated in the plant-wide simulator, namely Tennessee Eastman Process. Two condition modes of the simulation are used in this study, i.e. normal and upset condition with valve stiction problem. The PI-Fuzzy controller shows the effectiveness under these two conditions because the controller can reach the set-point targets in a fast time and produce small MSE of the two final products.
