Precise logic controllers with steptime fuzzification algorithm of input parameters.

In this paper, logical controllers, their scope of application as a type of intelligent control and classification were considered. Precise logic controllers with a step-time algorithm for fuzzification of input parameters were also considered as an attempt to eliminate the main disadvantages of logic controllers with an anytime-algorithm. A logical scheme was given that implements the step-time algorithm for fuzzification of a continuous physical quantity and an analysis of expressions was carried out to increase the speed of the fuzzifier and controller with the step-time algorithm, respectively, due to the development of a system of production rules to a rule whose antecedent at the current time is equal to a logical unit, from which it is concluded that the speed of precise logical controllers with step-time algorithm has increased due to the lack of a search procedure in the system of production rules, rules with an antecedent, equal at a given time to a logical unit. Although in case of an unsuccessful arrangement of the rules in the fuzzifier production system (the rule with the highest response frequency is located at the end of the production system), the increase in the speed of the controller may be insignificant.
