Programmable controller with fuzzy control function, fuzzy control process and fuzzy control monitoring process

摘要

A process for monitoring fuzzy control information of a programmable controller having a fuzzy control function and at least one input converting module and/or output converting module by using a fuzzy control monitoring device. This process includes the steps of defining fuzzy membership functions, fuzzy output functions and/or fuzzy result functions using a format comprising a plurality of points, and storing data representing these functions in at least one of the input converting modules and/or output converting modules. Data is generated which includes first fuzzy grade numbers, second fuzzy grade numbers and/or a composite fuzzy set based on the functions. The process further includes the step of monitoring production of the generated data by using the monitoring device. Another control monitoring process of the invention includes the steps of connecting a plurality of programmable controllers comprising at least an input converting module and/or an output converting module, by a network, and storing at least one fuzzy control function in at least one of the input converting modules and/or output converting modules. The process further includes the step of monitoring the fuzzy control information of the plurality of programmable controllers using a single fuzzy control monitoring device coupled to the network.
