Fuzzy controller developed in a PLC, based on weighted average method

Abstract:

The industry control solutions are generally base on a Programmable Logic Controller (PLC), however implementations of Fuzzy Controllers for complex systems which control is based on a fuzzy system has been a disadvantage since not all PLC's have specific modules for this purpose. This work proposes a procedure for the implementation of Fuzzy Logic Controller (FLC) on a PLC without the use of any specific module. The FLC assumes a Mamdani-based inference and defuzzyfication of Weighted Average Method (WAM) with two inputs and one output. Simulation and experimental validation are carried out in order to verify the effectiveness of the FLC designed.
