CONTROL OR REGULATING SYSTEMS IN GENERAL; FUNCTIONAL ELEMENTS OF SUCH SYSTEMS; MONITORING OR TESTING ARRANGEMENTS FOR SUCH SYSTEMS OR ELEMENTS (systems for controlling or regulating non-electric variables G05D; systems for regulating electric or magnetic variables G05F; control devices or systems insofar as characterised by mechanical features only G05G)

Introduced: September 1968

Description

G05B covers general-purpose control and regulating systems, encompassing feedback mechanisms, closed-loop controllers, and functional components applicable across industrial and technical domains. This subclass includes control system theory, functional elements (sensors, actuators, controllers), and diagnostic or testing apparatus for verifying system performance. It addresses both mechanical and electromechanical control solutions, as well as the methodologies for monitoring system operation, but excludes subject-specific control systems assigned to other G05 subclasses (such as G05D for particular regulated variables like speed or temperature) and systems integrated with their end applications in specialized technical fields.
