IMPLEMENTATION OF THE METHOD OF FUZZY CONTROL OF THE RECTIFICATION PROCESS BASED ON FUZZY LOGIC

The method of controlling the rectification process using fuzzy control based on fuzzy logic is studied. The structural scheme of the rectification process control system based on fuzzy logic is proposed. The analysis of the operation of the fuzzy rectifier is also carried out by comparing the human with the elements of fuzzy thinking. It is shown that the logical thinking of the human is similar to the functions performed by the fuzzy rectifier and the work of the components of the intellectual control system. The terms of linguistic variables are presented to reflect the rectification process of multi-component mixtures. The principle of the reference model control and the structural scheme of the fuzzy control system are given. Based on the obtained equations, expressions for the membership functions are written and an algorithm used to implement fuzzy control is proposed. To compare the performance of the fuzzy PID-controller control system and the traditional PID-controller control system, a structural scheme is constructed and transition process graphs are constructed and compared.
