Abstract:
The overwhelming number of modern adjustable electric drives use adaptive vector control. Various models and control methods used for various purposes were developed. The progress of digital technology has allowed the use of more complex and effective methods of control. The article proposes an induction motor control by adaptive vector control method. The optimal adaptive observer for adaptive control of the electric drive is used in the flux control loop. A mathematical model has been compiled, with the help of which the transient operating modes of the electric drive have been investigated. The investigation shows the effectiveness of the proposed control method.

Abstract:
Modern induction electric drives usually use vector control, due to which their characteristics are improved. The purpose of most studies are the problems associated with the identification and estimation of the parameters of electric drives at zero speed and close to it. The article proposes an adaptive control in the control loop of the torque. For adaptive control, an optimal adaptive observer is used. A mathematical model of the electric drive, with which the modes of operation were investigated, was created.
