Thanks to the advancements in processor industry, popularity industrial applications of Finite control set model predictive (FCS-MPC) is increasing. FCS-MPC has several advantages, such as high closed-loop bandwidth, inclusion constraints, and nonlinearities. However, signals are directly produced by controller since no modulator used. Hence, system non-fixed switching frequency, maximum achiev...

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...

A simple maximum torque per ampere (MTPA) method is designed for interior permanent magnet synchronous motors (IPMSMs) with no current control.

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...
