Interior permanent magnet synchronous machines are unavoidably subject to production tolerances. Quantities like permanent magnet flux or air gap thickness of a machine may deviate with regard to their nominal parameter values. Driven with a conventional torque control strategy this leads to inaccuracy of the output torque. Especially for traction drives in road vehicles, significant torque err...

Small Permanent Magnet Synchronous Generators (PMSGs) are widely used in small rooftop wind turbines. In order to inject the electric power generated by PMSG, into grid, a back-to-back AC/DC/AC converter is required. this paper, low cost with high efficiency proposed for rectifier stage obtain maximum per ampere of PMSG. This structure based on Discontinuous Conduction Mode Single-Ended Primary...

Abstract A new field-oriented control strategy for induction motor is proposed in the paper. It called Maximum Torque Per Watt (MTPW) and allows obtaining minimum value of sum stator rotor losses due to joule effect, iron losses, a given reference torque speed. Iron have been modeled according Steinmetz equation, separating hysteresis eddy currents taking into account dependence both on frequen...

This paper presents a detailed recent research trend on multi-phase induction machines, which include multiphase induction motor as well as the multiphase induction generator. Electrical power system developed so far was of three phases since the beginning of the last century but research in the field of multi-phase machines have attracted increased interest in recent years due to the several a...

To improve the motor efficiency and expand actual external characteristic region of electric vehicle permanent magnet synchronous (PMSM) drive systems, optimal operation mapping torque to d-q axis current is usually applied. Nevertheless, it difficult deal with complex mechanism factors such as parameter saturation temperature change for traditional optimization method based on basic voltage eq...

This article presents an evaluation of simplified model considering only q-axis current effects on parameters for rapid identification and control development interior permanent magnet (IPM) traction machines. It is shown that the simple easy to be implemented. demonstrated in low-speed region with maximum torque per ampere (MTPA) control, due flat segment around MTPA point relevant constant ov...

This paper presents a novel Brain Emotional Learning Based Intelligent Controller (BELBIC) for controlling some of the parameters, such as speed, torque, quadrature and direct axis current and voltage of an Interior Permanent Magnet Synchronous Motor (IPMSM). PI controllers are widely used as speed controllers in industries. IPMSMs are characterized as complex, highly non-linear and time-varyin...

Some major problems in the motor drive are overshoot or undershoot of transient response characteristics and a parameter mismatch due to magnetic saturation. This study proposed 3D inductance map combined with maximum-torque-per-ampere (MTPA) based on finite-element (FE) model considering cross-coupling saturation impact overcome this problem. The FE has high accuracy no-load back electromotive...

Due to the expected increase in electric vehicles (EVs) sales and hence of price rare-earth permanent magnets, switched reluctance motors (SRMs) are gaining increasing research interest currently future. The SRMs offer numerous advantages regarding their structure converter topologies. However, they suffer from high torque ripple complex control algorithms. This paper presents an improved direc...
