A maximum torque per ampere vector control strategy for synchronous reluctance motors considering saturation and iron losses

Relevance of Including Saturation and Position Dependence in the Inductances for Accurate Dynamic Modeling and Control of SynRMs

“…Several mathematical and analytical methods to set the value of id* can be found in the literature e.g. [6], [9] and [12]. However, these methods have several assumptions e.g.…”

“…Citation information: DOI 10.1109/TIA.2016.2614954, IEEE Transactions on Industry Applications 2 SynRM performance and control. Several models have been suggested to include the effect of the magnetic saturation for electrical machines [5]- [12]. For example, in [6], mathematical relations based on experimental measurements were proposed to include the magnetic saturation effect of the dq-axis inductances of the SynRM.…”

“…In [11], the impact of cross saturation in SynRM of transverse-laminated type is studied with a mixed theoretical and experimental approach considering assumptions in the measuring of the dq-axis fluxlinkages relations. In [12], the authors obtained Ld as function only of id by experimental measurements, neglecting the crosssaturation effect. In addition, they assumed constant Lq.…”

Direct Torque Control of Synchronous Reluctance Motor Using Feedback Linearization Including Saturation and Iron Losses

“…In [10], the motor parameters are online estimated on the basis of (RLS) method, only using the proposed mathematical method and motor measured currents and voltages. In [11], the iron losses resistance is obtained by no load test and the magnetic saturation is considered through a lookup table which shows the variation of direct axis inductance versus direct axis current while the little effect of magnetic saturation on parameter L q is ignored.…”

Control Scheme for Wide-Speed-Range Operation of Synchronous Reluctance Motor in M-T Frame Synchronized with Stator Flux Linkage

“…Maximum torque per ampere (MTPA) control and flux-weakening (FW) control are applied for wide speed range operation. Many methods of achieving such controls have been reported, and these methods are based mainly on a mathematical model of the rotating d-q reference frame that is synchronized with the rotor (1)- (4) . Direct torque control (DTC) can be applied to motor drive systems regardless of the category of motor (5) (6) .…”
