Özet

Programmable Logic Controllers are microprocessor based control systems which manage a machine or an industrial foundation by means of change of situations and a program edited before. Basically, a PLC is composed of a microprocessor, a power supply and input/output units (Kurtulan S., 1996). Beside these units mentioned above, some certain units were developed which respond to requirement of faster and more effective processing in industrial controlling systems. These special units, such as high speed counters, heat controllers  and pH controllers increase the controlling performance of PLCs. Application of fuzzy logic theory in control systems proved to be superior to the conventional control systems. Fuzzy logic controllers can infer coherent results in uncertain conditions when it is unnecessary to control a complex system which is impossible to model using mathematical ways. In this paper, the applicability of a special unit to PLCs were investigated which is controlled by a software that performs fuzzy logic processes, by means of improvement on a real industrial system.
