ELECTRIC DRIVE WITH INCREASED SENSITIVITY TO DEVELOPMENT OF SMALL ANGULAR ROTATION SPEEDS Russian patent published in 2019 - IPC H02P21/06 H02P27/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in control systems for development and adjustment of specified angular rotation speed of a control object in a wide range: from thousandths of degrees per second to hundreds of degrees per second. In an electric drive consisting of an engine, a gear drive, feedback sensors, an electronic unit and a control object, two angular position sensors are placed along the rotation axes of the control object and the rotor of the actuator and integrating preset angular rotation speeds of the control object and the rotor of the engine, closing the two control loops along the rotation axes of the control object and the rotor of the actuating motor, calculating mismatch signals, analyzing the value of the specified angular rotation speed of the control object, recording the transition of the boundary value of the specified angular rotation speed of the control object, selection of control circuit, recalculation of current values of integrator of preset angular speed of rotation of selected control loop, change of coefficients of control device. As per the output signal of the regulator, the engine is provided with angular speed of rotation for its further transmission to the control object.

EFFECT: increased sensitivity of mining of the specified angular speed of rotation of the control object in the mode of low rotation speeds without increase in the angular position sensor capacity.
