Abstract

AN ADAPTIVE PD CONTROLLER WAS DESIGNED TO CONTROL THE TEMPERATURE OF THE CONDENSER OF A POLYETHYLENE TEREPHTHALATE REACTOR. THREE FORMS OF TRANSFER FUNCTIONS WERE DERIVED FOR THE CONDENSER. THE COEFFICIENTS OF TRANSFER FUNCTIONS WERE CALCULATED BY ITAE METHOD. A DIGITAL FILTER WAS SUCCESSFULLY USED IN ORDER TO OVERCOME THE OSCILLATORY BEHAVIOR OF TEMPERATURE. IN ADDITION, A SET OF PD AND PID CONTROLLERS WERE DESIGNED, BASED ON ITAE METHOD, TO TRACK THE TEMPERATURE TRAJECTORY. THE PERFORMANCE OF THE CONTROLLERS WAS COMPARED AND FIGURED OUT THAT PD CONTROLLERS HAVE BETTER EFFICIENCY. HENCE, AN ADAPTIVE PD CONTROLLER WAS APPLIED TO SYSTEM. THE CONTROLLER SHOWED THE MAXIMUM DEVIATION WAS ABOUT 0.5 ◦C AROUND 160 OC.
