Precision control of refinery feed-heater temperature using fuzzy algorithm

Abstract

We present an easily implementable control strategy using fuzzy algorithm for refinery feed-heater temperature control. Feed-heater exhibits large amounts of transportation lag making all conventional control methods inadequate. The fuzzy algorithm for real time implementation has been successfully developed and tested using a process model on an IBM PC.Simulation results indicate that the controller can be applied to dead time and nonlinear processes.
