Implementing SVPWM technique to Axial Flux Permanent Magnet Synchronous Motor Drive with Internal Model Current Controller

摘要

This paper presents a study of axial flux permanentmagnet synchronous motor (AFPMSM) drive system. Aninternal model control (IMC) strategy is introduced to controlthe AFPMSM drive through currents, leading to an extension ofPI control with integrators added in the off-diagonal elements toremove the cross-coupling effects between the applied voltagesand stator currents in a feed-forward manner. The referencevoltage is applied through a space vector pulse width modulation(SVPWM) unit. A diverse set of test scenarios has been realizedto comparatively evaluate the state estimation of the sensor-lessAFPMSM drive performances under the implemented IMC-based control regime using a SVPWM inverter. The resultingMATLAB simulation outcomes in the face of no-load, nominalload and speed reversal clearly illustrate the well-behavedperformances of IMC controller and SVPWM technique to anAxial Flux PM Motor Drive system.
