AUTOMATIC CONTROL METHOD OF PARAMETRES OF ELECTRIC MECHANICAL SYSTEM AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC H02P7/292 G05B11/01 

FIELD: electricity.

SUBSTANCE: automatic control method consists in measurement of current and speed of DC motor, restriction of current signal with non-linearity of "dead zone" type and voltage control of armature chain of DC motor as per structure of summing amplifier with intensity selector, interruption of action of intensity selector and feedback as per the speed at actuation moments of current cutoff, and integration of control signal prior to its supply to summing amplifier. Device intended for the method's implementation includes thyristor converter, current sensor, intensity selector, adder, speed sensor, summing amplifier, non-linear and linear elements of current cutoff circuit. Besides, relay unit, zero arrangement unit and integrator is introduced to it.

EFFECT: improving control process accuracy.
