G05F - Systems for regulating electric or magnetic variables

More topics under "G05F - Systems for regulating electric or magnetic variables" (51,839)
G05F 1 - Automatic systems in which deviations of an electric quantity from one or more predetermined values are detected at the output of the system and fed back to a device within the system to restore the detected quantity to its predetermined value or values, i.e. retroactive systems (37,749)
G05F 3 - Non-retroactive systems for regulating electric variables by using an uncontrolled element, or an uncontrolled combination of elements, such element or such combination having self-regulating properties (12,739)
G05F 5 - Systems for regulating electric variables by detecting deviations in the electric input to the system and thereby controlling a device within the system to obtain a regulated output (1,182)
