Electrical line-shafting control for permanent magnet synchronous motors using active disturbance rejection control

Abstract

Abstract This study presents an electronic line-shafting (ELS) control strategy based on Active Disturbance Rejection Controler (ADRC) for permanent magnet synchronous motor systems. In order to improve the speed synchronization accuracy of the system when startup and a disturbance occurs, the TD of ADRC is used to arrange the same transition process for each drive unit. In addition, the ESO (Extended State Observer) in ADRC is used to observe the load disturbance of each drive unit and give feedback to the virtual line-shafting, thus the system obtained high speed synchronisation. Effectiveness of the proposed ELS control scheme is verified by experiment results.
