Abstract
The parametric synthesis of the sensorless vector control system of an induction motor (IM) of electric vehicle with the rotor speed observer, which is constructed according to the structure of the model reference adaptive system, is made. Through mathematical modeling, the dynamical properties of the synthesized system in operating modes, which are characteristic for a traction drive of an electric vehicle, are investigated. To improve the system, an algorithm for the speed observer adaptation mechanism has been upgraded. Due to this, in the sensorless control system of IM improved quality and reduced energy losses in transient processes caused by changes in motor load. References 10, figures 7, table.
