ELECTRIC DRIVE Russian patent published in 2020 - IPC G05B13/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to electric drives with reference models and PID-regulators, and can be used in precision electromechanical systems. Electric drive comprises main electric drive with input adder (1), first input of which is input of electric drive, reference model, outputs of main electric drive and reference model are connected to inputs of output adder (5). Output of input adder is connected to inputs of proportional (6) and differentiating (7) links, outputs of which are connected to first, second inputs of adder (2), connected in series to power amplifier (8) and electric motor (9), mechanically connected to control object (10) and angle sensor (11), which output is connected to adder (1) second inverting input. Reference model comprises adder (3), first input of which is connected to electric drive input, and output is connected to inputs of models of proportional (12) and differentiating (13) links, outputs of which are connected to inputs of adder (4), connected in series to models of power amplifier (14) and electric motor (15), connected to models of control object (16) and angle sensor (17), output of which is connected to second inverting input of adder (3) and to first input of output adder (5), second inverting input of which is connected to output of angle sensor (11), and output is connected to input of integrator (18), output of which is connected to third input adder (2).

EFFECT: result is electric drive with improved dynamic characteristics and high accuracy.
