The implementation and comparison of differenttype self-tuning algorithms of fuzzy pid controllers on PLC

In this study, peak observer, function tuner and relative rate observer based self-tuning methods that adjust the input scaling factor corresponding to the derivative coefficient and the output scaling factor corresponding to the integral coefficient of the PID type fuzzy logic controller are implemented on PLC. The results of the three different self-tuning fuzzy PID-type controllers are compared with each other.
