2. 1. On Control of Back-to-Back Converters and Sensorless Induction Machine Drives

   Author : Rolf Ottersten; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active filtering; flux estimation; sensorless control; induction motor; back-to-back converter; pulsewidth-modulated rectifier; virtual flux; vector current control;

   Abstract : This thesis focuses on design and analysis of the control system structure for back-to-back converter squirrel-cage induction machine drives. Particularly, sensorless control of induction machines, meaning vector control without a mechanical shaft sensor, and vector control of pulsewidth-modulated (PWM) rectifiers are considered.
