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...

In this paper, a novel unity power factor (UPF) hysteresis current control method for surface-mounted permanent magnet synchronous motor (SPMSM) drive system is presented. The optimum voltage vectors, which are selected from a switching table according to the magnitude and phase of the stator current vector, are applying to the voltage source inverter (VSI). The UPF operation for SPMSM is achie...

This paper proposed a robust chaos control scheme for surface permanent magnet synchronous motor (SPMSM) drive system considering the uncertain parameters and external disturbances. A nonlinear time delay estimator is utilized to estimate the nonlinearities, uncertain parameters and disturbances of the system on line, so it is not necessarily required the exact model of the system. Then, based ...

The eddy current loss in the magnets of permanent magnet (PM) motors in a hybrid electric vehicle (HEV) and plug-in HEV is usually not taken into consideration in traditional motor design and analysis. However, due to the high conductivity of the rare-earth magnet, neodymium-iron-boron (NdFeB), and slot/tooth harmonics, there is eddy current loss generated inside the magnets. This loss may not ...

A novel d-axis variable-structure control (VSC) current regulator is proposed for realizing fast and accurate sensorless in the surface-mounted permanent magnet synchronous motor (SPMSM) this article. In regulator, sigmoid function employed as a switching law to reduce chattering effect increase degrees of freedom tuning regulator. The performance under VSC testified by using model reference ad...

A surface-mounted permanent magnet synchronous motor (SPMSM) is an electric with a simple magnetic circuit design, fast responsiveness, linear torque–current characteristics, speed–voltage and constant operating speed. SPMSMs use only torque; however, interior PMSMs (IPMSMs) have high power densities because they can reluctance torque. In addition, when flux-weakening control used, the range wi...

Axial flux motors have been in the focus of many research work due to their promising properties when compared conventional radial machines. permanent magnet synchronous (AFPMSM) studied literature were mostly limited surface-mounted machines (SPMSM), excluding only a few studies about axial internal (AFIPM) or magnet-assisted reluctance (AFPMaSynRM) Since numerous rotor topologies proposed and...

When the Surface-Mounted Permanent Magnet Synchronous Motor (SPMSM) is in condition of high-speed and low carrier-wave ratio, performance sensorless control more affected by digital delay, parameter inaccuracy, other factors. This paper presents a method based on static error between discrete d-axis current corresponding reference value. If there no position angle, should have approximately. In...

In this paper, a tracking differentiator-proportional integral and derivative (TD-PID) control scheme is proposed to the speed of surface mount permanent magnet synchronous motor (SPMSM). The TD used generate necessary transient profile for both reference output speed, which are compared with each other produce error signals that feed into PID controller. addition unit parameters, controller’s ...
