SELF-TUNING ELECTRIC DRIVE Russian patent published in 2015 - IPC G05B13/00 

FIELD: electricity.

SUBSTANCE: self-tuning electric drive comprises in-series first summator, correcting device with amplifier, electric motor with reducing gear, which output shaft is coupled to speed sensor, which output is connected to the first input of the first summator, which second input is connected to input of electric drive, in-series current sensor of the electric motor armature winding, the second summator and integrator. It contains auxiliary third summator, which first input is coupled to integrator output, its second input is connected to output of speed and its output is connected to the third input of the first summator and second input of the second summator, which third input is connected to output of speed sensor while its fourth input is coupled to output of the correcting device.

EFFECT: ensured nonsensitivity of the electric drive operation to distorted readings of the drive shaft speed sensor due to generation of auxiliary control action supplied to input of the electric drive thus maintaining its working efficiency in process of operation.
