The article deals with synthesis of a traction induction motor observer. The observer is one of the most important elements of the field-oriented traction motor control system. It largely determines such control measures as speed, accuracy and lack of fluctuation. The electromagnetic torque regulation of a traction induction motor mut be done at high speed for efficient use of conjunction of a wheel and a rail. Therefore, the feasibility of using an adaptive Luenberger filter as a traction induction motor observer was investigated. Its application allows determining the stator current, flux linkage of the rotor and the angular velocity of rotation of the rotor only by measuring electrical quantities, without a speed sensor. The possibility of assessing the change in the active resistance of the stator and rotor and the moment of resistance on the shaft of the traction motor were investigated. Mathematical modeling methods were used to examine the work of the observer on the example of the traction engine of the main electric locomotive. The start of the state identifier with zero initial conditions has been made and investigated when connecting to a running traction motor and changing the angular speed of rotation of the rotor. The use of observer based on the adaptive Luenberger filter allows receiving information about the work of the traction motor with the precision required for the efficient operation of a field-oriented control system.
