GUIDANCE DRIVE Russian patent published in 2022 - IPC F41G5/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of automatic control systems and pertains to a guidance drive. The drive comprises a giving apparatus, an electric machine amplifier, an actuating direct current electric engine, an adder, a pulse-width modulator, a differential amplifier, and a nonlinear correcting link with variable steepness. The terminals of the armature of the actuating electric engine are connected with the longitudinal brushes of the armature of the electric machine amplifier. The first input of the adder is connected with the output of the giving apparatus, and the output is connected with the input of the pulse-width modulator. The first and second outputs of the pulse-width modulator are connected with the second terminals of the first and second control windings of the electric machine amplifier. The third output is connected with the first terminals of the first and second control windings of the electric machine amplifier, closed with each other. The first and second inputs of the differential amplifier are connected with the first longitudinal and transverse brushes of the armature of the generator of the electric machine amplifier. The input of the non-linear correcting link is connected with the output of the differential amplifier, and the output is connected with the second input of the adder.

EFFECT: increase in the reliability and smoothness of operation of the drive at low guidance rates.
