What is the difference between fuzzy PID control and traditional PID control?

Fuzzy PID is three parameters of PID set by fuzzy logic algorithm, which has adaptive characteristics. The three parameters of PID will be automatically adjusted according to the change of external environment to ensure the stability of the control system, while the three parameters of traditional PID are unchanged and have no adaptive characteristics. Fuzzy PID is an intelligent PID, which has been successfully applied in engineering with satisfactory results.
