DC MOTOR CONTROL DEVICE Russian patent published in 2000 - IPC

FIELD: electrical engineering. SUBSTANCE: DC motor control device (known as automatic two-fold DC drive control system) that has current and speed sensors is provided, in addition, with voltage sensor, four aperiodic units, integrating unit, three proportional units, and three inertial differentiating units. Proposed motor is distinguished by zero static error in current regulation, minimal error in speed governing when following up control signal, two- and eight-fold increase in speed of response of current and speed control circuits, respectively, ten-times reduced dynamic error in speed control during stepped external action on load, zero static error in speed control same as that of prototype. EFFECT: improved reliability and precision of speed control. 1 dwg
