METHOD AND DEVICE OF DIGITAL PROCESSING OF SIGNALS FROM PULSE SENSOR OF ROTOR MOVEMENT IN ELECTRIC MOTOR-ENCODER Russian patent published in 2014 - IPC H02P25/00 B60L15/00 

FIELD: engines and pumps.

SUBSTANCE: group of inventions relates to the method and device of digital processing of signals from a pulse sensor of rotor movement in an electric motor-encoder, which may be used in an electric drive, in particular, a thrust electric drive of vehicles of different type and purpose. To process information about angular position of the rotor, an observer is used to observe mechanical variables of electric drive condition and a predictor, for functioning of which they previously before start of electric drive operation they set initial values of angular position of the electric motor rotor equal to zero, as well as values of angular speed of rotor rotation and load moment on the electric motor shaft, and an initial correcting signal of the predictor. During each cycle of calculations they produce a measured value of the angular position of the rotor, calculate the preliminary value of the correcting signal of the predictor. Further they produce the value of the correcting signal of the predictor and determine the value of the angular position of the rotor predicted for the start of the next cycle of calculations.

EFFECT: increased accuracy of assessment of angular position and angular speed of electric motor rotor rotation, which makes it possible to considerably improve characteristics of a drive control system.
