The purpose of the paper is to present the potentialities in terms of the control of a new kind of PM synchronous machine. With five phases and electromotive forces whose first (E1) and third (E3) harmonics are of similar amplitude, the studied machine, so-called bi-harmonic, has properties that are interesting for traction machine payload. With three-phase machines, supplied by a mono-harmonic...

This article presents an enhanced flux weakening (FW) control scheme for permanent magnet synchronous motors, focused on electric vehicle applications. The novelty of the proposed algorithm is integration in a unified both accelerator pedal as torque reference and cruise speed limiter limit, without interfering between them until this limit achieved. <italic xmlns:mml="http://www.w3.org/1998/Ma...

In this paper, the speed tracking problem of interior permanent magnet synchronous motor (IPMSM) an electric vehicle is studied. A cascade control strategy based on active disturbance rejection (ADRC) and a current improved duty cycle finite set model predictive (FCSMPC) are proposed, both which can reduce torque ripple as well computational burden. First all, in linearization process, some non...

This paper studies the optimal design and control scheme of a spoke-type interior permanent magnet motor (SIPM). An asymmetric rotor structure with flux barriers is designed to improve torque density SIPM. The method improves by approximating maximum value magnetic reluctance torque, wherein components are separated frozen permeability (FPM) evaluate contribution. does not increase amount magne...

Abstract: High-efficiency permanent-magnet synchronous machine (PMSM) drive systems need not only optimally designed motors but also efficiency-oriented control strategies. However, the existing control strategies only focus on partial loss optimization. This paper proposes a novel analytic loss model of PMSM in either sine-wave pulse-width modulation (SPWM) or space vector pulse width modulati...

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 new method to optimize, from working cycle defined by torque and speed profiles, both the design control strategy of permanent magnet synchronous generators (PMSGs). The case 10 MW direct-drive generator for an Offshore wind turbine was chosen illustrate this method, which is based on d–q axis equivalent circuit model. It allows with reduced computation time, design, consi...
