Optimum control method for process

Abstract

Abstract PURPOSE:To perform process control by PID operation speedily in the best state by reasoning an adjusting method corresponding to the damping ratio and sampling ratio of an answer pattern by a fuzzy adjustment rule table and performing the process control based on the reasoning result. CONSTITUTION:For example, there is a disturbance or input for command variation, etc., and a process 10 indicates an answer pattern having a large damping ratio and a sampling ratio when the process control is started. In this case, an operator inputs this answer pattern to an argument processor 30. This argument processor 30 is provided with many kinds of answer patterns which are generated previously and materials including adjusting methods corresponding to the answer patterns and an adjusting method corresponding to the answer pattern inputted by said operator is found based on the fuzzy adjustment rule table. Consequently, an argument about whether proportional sensitivity Kp and integration time Ti during the PID operation of a controller 20 are decreased greatly or not is made.
