Pembangunan Kawalan Logik Kabur dalam Reaktor Lapisan Terpadat (Development of Fuzzy Logic Controller for Packed Bed Reactor)
Journal Title: Jurnal Kejuruteraan - Year 2014, Vol 26, Issue 1
Abstract
Fuzzy logic control system on simulation model was created using MATLAB Simulink R2011a in order to control the isomerization process of glucose to fructose in recycled and non-recycled packed bed reactor. Immobilized glucose isomerase catalysts the process along with regulation of pH and temperature. Mathematical equations on rate of fructose production, temperature changes and pH changes were created and modulated into a simulation model. Fuzzy logic controller was applied onto this simulation model to control the pH and temperature. The calculated error from fuzzy logic control system was compared with PID control and ON/ OFF control at constant pH (pH 8) and temperature (60°C) respectively. Fuzzy logic control system was found to exhibit lower error compared to ON/OFF control system in both non-recycled and recycled packed bed reactor. The same fi nding was obtained on camparison to PID control system. Conserving pH and temperature at optimum conditions are important for an effi cient process. Thus, lower calculated error of fuzzy logic control indicated its potential in regulating isomerization process of glucose to fructose in packed bed reactor.
