JET-PHOTOCOMPENSATION INTEGRAL CONTROLLER Russian patent published in 2022 - IPC G05B11/40 

FIELD: electrical engineering.

SUBSTANCE: jet-photocompensation integral controller consists of a galvanometer with spreaders located in the movable part thereof with a frame with a feedback current secured thereon, said frame being placed in the field of a permanent magnet, and an optical circuit including a light source, a condenser, a diaphragm directing the light beam onto the mirror rigidly fixed on the spreaders of the movable part, wherein the reflected light beam is incident on a double photoconductive cell, both halves whereof which are included in different arms of an electric bridge characterised by a plate being rigidly fixed on the spreaders, with two input nozzles associated with a variable and setting an adjustable parameter being located perpendicular to said plate, and an aperiodic link consisting of the electric capacitor and variable resistance for changing the integration time is placed in the galvanometer feedback.

EFFECT: higher speed due to the application of a compensation circuit based on the force action of a jet on a movable barrier.
