METHOD OF AND DEVICE FOR CONTROLLING ELECTRIC DRIVE Russian patent published in 1994 - IPC

Abstract RU 2020724 C1

FIELD: drives of machine tools, robots, servo systems of various applications. SUBSTANCE: method involves control of electric drive by varying inverter current to recover RMS value of phase current amplitude to be used as base for shaping compensating current including synchronous heat phase; by shifting compensating current phase variation in mentioned currents is compensated for. In checking torque generating line, feedback is provided according to current component determined by RMS value of phase current amplitude while shifting current phases. EFFECT: improved reliability of control. 3 cl, 1 dwg
