ABSTRACT:
A fuzzy feedback controller is designed as follows: A deviation between a process value and a set value, and a variation of the deviation are obtained with the aid of an arithmetic memory device, and the deviation and the variation of the deviation are normalized with normalizing devices. A fuzzy inference operating device performs a fuzzy inference by using the deviation and the variation of the deviation thus normalized, to obtain a control output variation. The control output variation is normalized with another normalizing device. The control output variation .DELTA.u thus normalized is added to the preceding control output in an addition device, to form a new control output, which is applied to an operating device. A parameter adapting device makes normalizing parameters adaptive according to the response waveform of the process value.
