Experimental results of sensorless rotor field oriented control using MRAS

摘要

This work deals with design and implementationudof sensorless rotor field oriented control using model referenceudadaptive system (MRAS) of induction motor (IM) drives.udSVPWM, using an injected Zero-Sequence Signal (ZSS), is usedudfor controlling the motor. Proportional Integral Controllersudwith antiwindup are designed. A 3Kw, 3-phase, 50Hz, 1420rpm,udinduction motor and a dSPACE DS1104 hardware/software areudused to carry out the control application. The experimentaludresults show the effectiveness and the limitation of the controludmethod
