PENGGUNAAN FUZZIPC DAN PENGALI FREKUENSI UNTUK MENGENDALIKAN KECEPATAN MOTOR DC

Abstract

Motor speed controller usually used in industrial, so alot of researches done to make better  speed control system. In this paper  the used of FuzzIPC (Driver Fuzzy logic for Festo) in controlling DC motor speed. As controller using Festo PLC FC34 type. Constraint of Festo PLC gives Pulse Width Modulation (PWM) that must use external frequency multiplier built using AT89C2051 WITH 12MHz that change PWM signal from PLC to give new PWM signal with higher frequency, but has the same duty cycle. Experiment result shows that frequency multiplier modul output has cbigger multipier factor cycle duty error.  The biggest error occur multiplier factor 250. FuzzyIPC used as controller algorithm can give a good control DC motor speed. Frequency multiplier must be revised still has big error. Non-accuracy system in calculating and speed of calculation done by microcontroller.
