Texto completoFuzzy control systems are largely applied at the processes control industry, usually controlling analogic variables, such as, pressure, temperature, outflow, position and speed. Nowadays, there are several market solutions which allow the Fuzzy Logic usage in PLCs (Programmable Logic Controllers), therefore, these solutions are proprietary and have a high cost. Additionally, there is the IEC 61131-7 standard, introduced in 2000, which specifies Fuzzy systems in PLCs. It defines a set of rules which allow the Fuzzy definition regardless of the hardware from the PLCs manufacturer. The adoption of the IEC 61131-7 standard is not happening effectively, due to many factors, but mainly because there are already proprietary and customized solutions provided by the PLCs manufacturers. The contribution provided by this report, is a method of Fuzzy control development by feedback using as solution, a free or open source code system. This method proposes the usage of a distributed control architecture involving both PCs (Personal Computers) and PLCs. The building of the Fuzzy controller was made in Java language and released under open source code license, allowing its use to be free in a great variety of industrial applications. The method is based on the IEC 61131-7 standard for the Fuzzy logic application in industrial automation. Several tests were performed, such as, software control table test, and even in a real plant for control software validation in a real operation. With the tests results were obtained quite a few response curves at time, which allow the evaluation of the controller and of the control software. After the tests executions and the verifying of the behavior obtained by the curves, it was stated the compatibility of the built software with the IEC 61131-7 standard, admitting it to be used in other applications.
