Abstract

Controlling a temperature for a large system is not an easy task, the lag is big and the overshoot is high. The conventional method of controlling this kind of process is not capable of giving satisfactory result. In this paper the implementation of Fuzzy Logic controller with Smith Predictor is an alternative to control this system. First order plus dead time model (FOPDT) is used for simulation. Fuzzy PD with Smith Predictor is developed using 3 (Fuzzy PD3-SP), 5 (Fuzzy PD5-SP) and 7 (Fuzzy PD7-SP) membership functions. With advantages of Smith Predictor and Fuzzy Logic Controller the purposed control structure is found better compared with conventional PID controller with Smith Predictor for controlling glycerin bleaching temperature.
