METHOD OF CONTROLLING DIGITAL ELECTROMECHANICAL SERVO SYSTEM Russian patent published in 2024 - IPC H02P7/00 

FIELD: machine building.

SUBSTANCE: according to the digital electromechanical servo system control method, voltage signals in the form of binary Gray codes δ_g1, δ_g2, δ_g3 of three discrete angle sensors are converted into a single voltage signal in the form of a feedback Gray code, converting it into a voltage signal in the form of a binary feedback code, comparing with a voltage signal in the form of a binary feedback code, generating a voltage signal in the form of a binary error code, compared with a given value of the voltage signal in the form of an accuracy code of maintaining the required position and supplied to the first and second motors of the electromechanical drive of the voltage system, thereby controlling the drives of the electric motors. During operation of the first electric motor, a high-frequency bipolar signal with amplitude A and frequency ƒ is supplied to the second electric motor, which excites micro-movements of its output shaft, shafts of brake and safety couplings, shafts of discrete angle sensors, shaft of the first electric motor.

EFFECT: reduced tracking errors of a digital electromechanical tracking system and increased accuracy of its tracking.
