Title:

DISTRIBUTED CONTROLLER AND SYSTEM AND CONTROLLER

Document Type and Number:

Japanese Patent JP2002049405

Kind Code:

A

Abstract:

To realize a controller having various control functions distributed control system.

This controller is composed of plural processors for executing numerical calculation, sequence calculation, neural network(NN), and fuzzy or the like. The controller is miniaturized by an LSI integration technique. Moreover, a processor function and an I/O function are made programmable so that flexibility can be increased. Then, a learning model such as a standard program whose programming is simple and the NN is integrated, and plural outputs to be calculated are weighted and added so that output data can be generated. Also, the value of weighting is updated according to learning. Thus, it is possible to realize distributed control system having various control functions such as the numerical calculation control, sequence control, NN application control, and fuzzy application control and a controller to be used for this system.
