Fuzzy logic predictive controller performance under variable time delay-a simulation study

In practice, phenol and formaldehyde are used to produce resin adhesives An unpredictable sudden heat is liberated by the nonlinear exothermal reaction even at room temperature. Classical PID control is one of the general solutions often applied in the industries to avoid temperature run-away and the consequent damage to expensive materials. However, due to the time varying nature of inherent time delay of the industrial plant, the PID method has been found to be a source of errors that affects the quality of the product. Therefore, in order to reduce the effect of inherent time delay, a predictive fuzzy logic control approach with adaptive loop is applied to the system. The paper discusses a detailed simulation study of the exothermal process based on experimental parameters using the MATLAB-SIMULINK toolbox.
