<p>PURPOSE:To provide the control system of high precision being well-adapted to behavior, in the process control containing a non-linear behavior. CONSTITUTION:A controller 1 is provided with a fuzzy inferring means 4 for inferring a predictor of a control purpose by a fuzzy model from process information, and an inference main mechanism 2 having a quantitative arithmetic means for calculating the predictor by an expression model, and for deriving selectively one of the predictors by the quantitative arithmetic means or the fuzzy inferring means by a result of deciding whether the process behavior is linear or non--linear. The decision of behavior is evaluated by a rule group with the degree of conviction for attaching importance to each of a quantitative type model and a qualitative type model by setting process information to a condition part. In accordance with a prediction of the model well-adapted to behavior of the process, a controlled variable for attaining a control purpose is outputted, therefore, there is an effect which can realize the control of with accuracy and a full time.</p> |
