FIELD: electricity.
SUBSTANCE: nonfuzzy logic control includes fuzzificator with seven inputs, logic output unit with specified membership functions of nonfuzzy terms of variables, to the output of which there supplied are input and output variables, as well as discrete input and output variables of control object, defuzzificator, actuator, control object and feedback sensor. Comparison device is implemented as the part of conventional part of production rules of fuzzy logic output unit. In order to improve the accuracy and quick action, input and output variables of the control are represented with a set of nonfuzzy terms, and additional increase in quick action of the control has been achieved by automatic location by means of ANY-TIME algorithm to the beginning of production system of rules with maximum actuation frequency. Enlargement of control functions of the control has been achieved due to application in antecedents of production rules of discrete input and output variables of control object. Invention provides automatic control of quick-acting processes described verbally and requiring the qualitative control, the time constant of which is less than response time of known logic controls.
EFFECT: improving quick action and accuracy; enlarging control functions of nonfuzzy logic controls.
