The traditional radial flux PMSM and axial have an effective air gap on only one side, between the stator rotor, generates electromagnetic torque. There are defects in magnetic-field utilization, it is difficult to improve torque density. Therefore, this paper proposes axial–radial-flux permanent-magnet synchronous motor (ARF-PMSM), which combines with flux, be used elevator-traction machine-dr...

Fuzzy logic is recently getting increasing emphasis in soft computing applications in the recent days. This paper presents an application of the fuzzy logic scheme to control the speed of an AC servo system & the same is proposed for a space vector pulse width modulation (SVPWM) inverter-fed permanent magnet synchronous motor (PMSM) drive. Based on the analysis of the PMSM transient response, a...

This paper presents the application of the Linear Quadretic Gaussian (LQG) controller to the state estimation and feedback of a speed sensorless permanent magnet synchronous motor (PMSM) drive system. The nonlinear model of the motor has been linearized on the basis of field orientation principle. The standard Kalman filter technique has been used to estimate the speed, position, and load torqu...

K. D. Hoang, Y. Ren, Z.Q.Zhu*, M. Foster Abstract—The switching-table-based direct torque control strategies (ST-DTC) of dual-three phase permanent magnet synchronous machine (PMSM) drives are investigated in this paper. Owing to its inherited advantage of suppression of sixth harmonic torque pulsation, dual-three phase machine has attracted more and more interests among various sorts of multi-...

This paper proposes a digital hardware control of Permanent Magnet Synchronous Motor (PMSM) using a SiC MOSFET inverter implemented in a FPGA (Field Programmable Gate Array) device. High frequency is required using a SiC MOSFET inverter to obtain high response and good stability for speed control systems. Not only the switching frequency of inverter, but also the control frequency is achieved u...
