Abstract

See full text

An analogical inference apparatus for control system is disclosed in which, in order to be able to generate a control signal to a system, which is to be controlled, even when conditions to be premised are unknown, the degree of similarity between the detected control signal from a sensor incorporated in the system and one of the predetermined control conditions stored in a memory is estimated by estimation means, and then a control value is inferred in accordance with the result of the estimation.
