Feedback Linearization Based Nonlinear Control of SynRM Drives Accounting for Self- and Cross-Saturation

This article proposes a nonlinear controller based on feedback linearization (FL) for synchronous reluctance motor (SynRM) drives which takes into consideration the magnetic saturation. The proposed FL control technique has been developed starting from theoretical definition of an original dynamic model SynRM taking both self- and cross-saturation effects. Such permits dynamics speed axis flux loops to be maintained constant independently load saturation iron core in variable direct operating conditions. Finally, sensitivity performance versus variation main parameters verified. tested experimentally suitably test setup. further compared with classic field-oriented (FOC) working
