This article presents a modeling approach and control strategy for multiphase surface-mounted permanent magnet synchronous machine drives. The mathematical model is completely general with respect to the parameters winding configuration. It also intrinsically considers effects of eventual constraints phase currents, generated from electrical connections among windings or resulting faults. curre...

In permanent magnet motors, the stator resistance and magnetic flux of change as temperature increases. These changes result in a maximum torque point per unit ampere (MTPA) motor. Without adequate compensation, this leads to decrease output torque. For reason, look-up table (LUTs) are prepared over range used for interpolation. This paper proposes method compensate reduction due increase using...

The conventional maximum torque per ampere (MTPA) operation usually neglects the derivative terms of interior permanent magnet synchronous motor (IPMSM) parameters, which significantly influences MTPA control accuracy. In this study, an scheme that considers is developed, and a parameter identification strategy inverter to be non-ideal developed for calculation IPMSM parameters terms. addition,...

Accurate torque control is of interest in traction and other industrial applications, whose realization challenged by parameters errors temperature-induced variations. This article proposes a sensorless technique for resilient salient synchronous machines. The position observer driven the adaptive projection vector error estimation (APP) scheme. A second vector, orthogonal to APP noninterferenc...

Multi-phase (more than three phases) drives possess several advantages over conventional three-phase drives such as: reducing the amplitude and increasing the frequency of torque pulsations, reducing the rotor harmonic currents, reducing the current per phase without increasing the voltage per phase, lowering the dc link current harmonics and higher reliability. By increasing the number of phas...

Permanent magnet machines have been used in the high-speed drive applications due to their high-efficiency, high-power-density, and wide-speed range characteristics.

This paper presents an analytical solution for the Maximum-Torque-per-Ampere (MTPA) operation of synchronous machines (SM) with anisotropy and magnetic cross-coupling for the application in wind turbine systems and airborne wind energy systems. For a given reference torque, the analytical MTPA solution provides the optimal stator current references which produce the desired torque while minimiz...

In this paper, an effective method to achieve accurate and efficient torque control of an interior permanent magnet synchronous motor (IPMSM) in electric vehicles, based on low-resolution Hall-effect sensors, is proposed. The high-resolution rotor position is estimated by a proportional integral (PI) regulator using the deviation between actual output power and reference output power. This meth...
