FIELD: automated electric drives.

SUBSTANCE: invention relates to an automated electric drive and can be used to build adaptive DC motor control systems. The method for determining the parameters of a DC electric motor consists in the fact that during the start-up and operation of the electric motor, the instantaneous values of current and voltage in the armature winding and the speed of the output shaft are simultaneously measured, then the measured instantaneous values of the current in the armature winding and the speed of the output shaft are differentiated, obtaining derivatives current in the armature winding and the speed of the output shaft, two time delays of the instantaneous values of the current in the armature winding and the speed of the output shaft and one time delay of the derivatives of the current in the armature winding and the speed of the output shaft, as well as the instantaneous values of the voltage in the armature winding are performed. The obtained current and delayed once and twice instantaneous values of current and voltage in the armature winding, the speed of the output shaft and the derivatives of the current in the armature winding and the speed of the output shaft are used to determine the active resistance of the armature winding and the inductance of the armature winding of the DC motor in real time. To determine the equivalent moment of inertia, reduced to the motor shaft, and the moment of load resistance on the DC motor shaft in real time, the stored current and delayed instantaneous currents and the derivative of the output shaft speed are used.

EFFECT: expansion of the arsenal of means of a similar purpose.
