This paper describes about a fuzzy logic control’s application on weight feeder conveyor. The plant represented by a third order transfer function. The designed fuzzy logic control had single input and single output. The crisp input of fuzzy logic control was an error signal and the crisp output was a speed of motor. The system was tested by a computer simulation using Matlab. Experiment results showed that fuzzy logic control could work well. The best rise time and settling time achieved by the system were 4 and 6 seconds respectively.
