METHOD, UNIT, AND SYSTEM FOR INTELLIGENT CONTROL BASED UPON SOFT CALCULATION

摘要

PROBLEM TO BE SOLVED: To decrease the number of sensors in use without a significant loss of control precision by constituting a 2nd control system by using a 1st and a 2nd control signal. ;SOLUTION: A sensor corrector 460 is used as a 1st adaptation function for (2nd genetic algorithm: GA2 444) and calculates information reference as the maximum of mutual information between two control signals xa and ya. An entropy model 442 gives physical reference as minimum entropy generation (used as 2nd adaptation function of GA2 444) by using the information from a sensor 482. The output of the GA2 444 is a tutor signal 447 for a fuzzy neural network(FNN) 2 486 and used on-line to generate the deletion control signal ya, so that the quality of a deletion control signal yb is similar to that of the optimum control signal xa. Then an optimizing device 440 provides the correction of the control signal ya for off-line inspection from the FNN 2 486 by using new information reference.;COPYRIGHT: (C)2000,JPO
