Abstract
BACKGROUND: Currently, the requirements to energy efficiency of transport vehicles are more and more tightened due to service cost reduction. Energy efficiency is the most relevant for them as it directly influences on the key feature — maximum mileage. Therefore it is necessary to control electric motors in a way to ensure maximal surface grip coefficient excluding propulsors’ slipping, as well as to establish operation modes of motors and switching between the modes to the one having the maximal efficiency. In this case, for effective control, it is necessary to define electromagnetic torque at the shaft of an electric motor and resistance torque at wheels rapidly for generating corresponding control and correcting exposures.
AIMS: Development of the theoretical basis and the law of estimation the electromagnetic torque at the shaft of a traction electric motor of transport vehicles for the sake of efficient control of traction electric drive and its diagnostics.
METHODS: Simulation of the observer of the electromagnetic torque at the shaft of a traction electric motor was carried out in the MATLAB/Simulink software package.
RESULTS: The article provides with theoretical basis of formatting the law of optimal estimation of the electromagnetic torque at the shaft of a traction electric motor of transport vehicles for the sake of efficient control of traction electric drive, its diagnostics, as well as the results of simulation the law of estimation of the electromagnetic torque at the shaft of a traction electric motor obtained in the MATLAB/Simulink.
CONCLUSIONS: Practical value of the study lies in ability of using the proposed observer for development of control system and diagnostics of transport vehicles.
