| description | Abstract The use of permanent magnet synchronous machine (PMSM) in vehicle propulsion systems is growing in prominence. The machines provide greater torque density and efficiency as a result of PMSM pre-excitation. However, because of their poor torsional vibration dampening, their intrinsic torque ripple may provide a challenge for electric vehicles (EVs) and degrade passenger comfort. This may prohibit the utilization of PMSM to increase the energy economy of vehicles. This paper proposed a speed-current adaptive proportional-integral-resonant (PIR) control strategy to reduce periodic torque harmonics and provide smooth speed control of the PMSM drive system. The effects of several non-ideal components on speed and current components are analyzed according to their location in the system. The components include rotor flux harmonics, cogging torque, inaccurate current measurement including offset error and scaling error, and inverter dead time error, these components all lead to periodic torque harmonics. In order to determine the best phase adjustment parameters for the resonant item to minimize speed-torque harmonics and ensure system stability, stability analysis is carried out to take into account the delays brought on by the current loop and speed loop. Consequently, the PMSM drive system’s stability, overall performance, and efficiency are enhanced due to the decreased harmonics in the speed and current loop. Ultimately, the findings of the simulation and real-time simulator utilizing the OPAL-RT OP5700 platform show that the proposed adaptive PIR control method successfully lowers the periodic speed-current harmonics THD values of the PMSM drive when compared to conventional control strategies. The proposed control system is more stable and efficient as a result of lower THD values. |
