JET-PNEUMATIC PROPORTIONAL-INTEGRAL-DIFFERENTIAL (PID) REGULATOR Russian patent published in 2022 - IPC G05B11/44 

FIELD: automatic regulators.

SUBSTANCE: invention relates to automatic regulators. The jet-pneumatic proportional-integral-differential regulator consists of two circuits with elements made in the form of plates suspended on gas supports, with reading devices represented by “nozzle-shutter” units covered by two compensation nozzles located before and after the pneumatic membrane power amplifiers that form regenerative feedback with a gain greater than one. One of the schemes is a proportional-integral regulator with two nozzles located on both sides of the plate. In the positive feedback of the regulator, there is a consumable integral link, consisting of a variable resistance, a constant volume, an accurate consumable follower and a nozzle. In another circuit, a differentiating link and a nozzle are located, associated with the output of the first circuit.

EFFECT: invention increases the accuracy of regulation.
