    Abstract: A method of controlling a process having dead time is disclosed. This method obtains input evaluating criteria for setting values of process response outputs in relation to known input information, the input evaluating criteria being represented in one or more of the integral, proportional and differential type process responses. Fuzzy inference is used to estimate a variation in the process response output occurring upon lapse of a dead time or a control amount relating thereto on the basis of the value of an input evaluating criterion. The process is subjected to fuzzy PI (proportional and integral) control based on the estimated value.
