Abstract :
A substantial portion of the literature on fuzzy control deals with the usage of fuzzy rules to implement PID type control and also fuzzy supervisory control. Fuzzy models have received significant attention from various fields of interest. Especially so called the Takagi-Sugeno-type fuzzy model which superbly describes a nonlinear system. In this paper we present implementation of universal fuzzy PS/PD function block implemented to the PLC Simatic S7 300/400. We also present implementation of universal function block of fuzzy expert system and PID regulator for PLC Simatic S7 300/400. Control system with implemented fuzzy expert system and PID regulator and control system with implemented PS/PD regulator with visualizations are designed.
