GUARNIZO LEMUS, Cristian. A method to implement a Takagi-Sugeno fuzzy controller using a PLC s7-300. Tecnura [online]. 2011, vol.15, n.30, pp.44-51. ISSN 0123-921X.

This paper presents a methodology for implementing fuzzy logic controllers based on a S7300 PLC using the programming language SCL (Structured Control Language) in STEP 7. We present the design of the fuzzy function, variable declarations, and the evaluation design of membership functions and rules of the fuzzy system. Since this scheme can be implemented more complex fuzzy models, such as adaptive or Auto tuner. We present an application example for a discrete time simulated in the PLC using a PI fuzzy controller.
