DIRECT CURRENT DRIVE WITH ELASTIC COUPLINGS

摘要

FIELD: electricity.SUBSTANCE: invention is related to the sphere of electric engineering and may be used in the control system for electric drives. The electric drive contains a rate setting unit, a speed control unit, a closed current control circuit with armature current sensor, electromechanical equipment of the motor, an actuator with elastic couplings and an actuator shaft speed sensor, an elastic torque sensor and a steady load sensor connected in-series. The speed control unit includes a differentiating element, seven scaling elements, a summing member and a zero-order interpolator. The first scaling element is connected to the rate-setting unit; the second scaling element is connected to the differentiating element; the third scaling element is connected to the input of the steady load sensor; the fourth scaling element is connected to the output of the armature current sensor which input is connected to the output of the closed current control circuit. The fifth scaling element is connected to the output of the motor shaft speed sensor; the sixth scaling element is connected to the output of the elastic torque sensor and the seventh scaling element is connected to the output of the actuator shaft speed sensor. The scaling elements are connected to inputs of the summing element.EFFECT: increasing operational speed and decreasing dynamic error during regulation of the actuator speed in the electromechanical system with elastic couplings.5 dwg
