Inductance Identification of Synchronous Reluctance Motors Using Capacitor Discharge Method

Current-Controller-Free Self-Commissioning Scheme for Deadbeat Predictive Control in Parametric Uncertain SPMSM

“…where Rs is the stator resistance, id and iq are the d, q-axis current feedbacks, ψf is the PM flux linkage, ud and uq are the d, q-axis voltages, and ωe is the electrical angular velocity. The stator inductances are categorized as d, q-axis incremental inductances (L inc and L app q ) [12]. For SPMSMs, if ignoring the magnetic saturation and cross-saturation effect,…”

“…But the inductance is a function of magnetic saturation [11]. When considering the inductance variation under the saturated effect, the concept of incremental and apparent inductances must be concerned [12]. The values of incremental inductances can be much less than those of apparent inductances at heavily saturated conditions [13].…”

Current Harmonics Controller for Reduction of Acoustic Noise, Vibrations and Torque Ripple Caused by Cogging Torque in PM Motors under FOC Operation

“…However, authors mentioned side effects of PIR controller during high dynamic operation. Another technique for torque ripple reduction with a single layer artificial neural network was introduced in [23,24]. This technique used only speer ripple or ripple in estimated torque to form compensation voltage.…”
