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...

Many control schemes have been proposed for induction motor and permanent magnet synchronous motor control, which are almost highly complex and non-linear. Also, a simple and efficient method for unified control of the electric moto are rarely investigated. In this paper, a novel control method based on rotor flux orientation is proposed. The novelties of proposed method are elimination of q-ax...

The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper presents the design and analysis...

Referring to the sensorless control of interior permanent magnet synchronous motor (IPMSM), initial rotor polarity is normally estimated based on saturation effect. However, for certain special IPMSMs, effect weak even at rated point, making saturation-based detection methods invalid. Therefore, this paper proposes a novel method torque-pulse injection. Two current pulses are imposed positive a...

This application note describes the design of a 3-phase Permanent Magnet Synchronous Motor (PMSM) vector control drive with 3-shunt current sensing with a position sensor. The design is targeted for automotive applications. This cost-effective solution benefits from a Freescale Semiconductor MPC5604P device dedicated for motor control.

A new permanent magnet design for axial flux interior permanent magnet (AFIPM) motor is described in this paper. Poleshoes are traditionally used to produce sinusoidal flux linkage and sinusoidal EMF especially in the case of radial flux synchronous machines. Poleshoes are not a practical solution in the case of axial flux PM machine. The use of poleshoes in the production of sinusoidal back EM...
