EN Issues related to the automatic selection of the PID controller settings have been known for several years. This article describes the concept of self-tuning using fuzzy logic block (FLB). The FLB represents expert knowledge and in the process serves as the master. It describes the advantages of the designed structure of fuzzy logic simulation system application. The paper contains block diagram descriptions of designed controller and control loop. The designed tuning algorithm bases on quality indicators and rule bases which was described as membership functions. The readjustment of the controller settings takes place in subsequent iterations of the tuning process. Simulation tests result of the proposed tuning system topology were presented. As the simulation environment was used Matlab Simulink.
