Fuzzy knowledge for controlling is generated in a converting means 9 based on the constant and is stored in a fuzzy knowledge storage means for controlling 14. A fuzzy knowledge correcting means 13 corrects a stored fuzzy control rule by a simplex method which is to set a simplex with the value of the consequent part of the generated fuzzy control rule as a base, to obtain a worst point with an ideal response in an ideal response storage means 10 as a reference and to obtain the reflection point. Thus, the fuzzy knowledge which can execute a good control is automatically generated and the PID constant is tuned to be optimum in such a way that control which is close to the ideal response is possible.
