Optimized Multi-Rate PI Control for PMSM Torque in HEVs

The embedded permanent magnet synchronous motor is becoming increasingly popular due to its excellent power density, high efficiency, and reliability for hybrid electric vehicles. To achieve the best performance of the vehicle, EPMSM should possess energy efficiency, torque control, and smooth driving is most anticipated. This suggested work demonstrates an advanced torque management technique for EPMSM with a focus on optimizing torque production and by minimizing the loss of energy in hybrid electric vehicles. This merges the vector control methods with a field-oriented control (FOC) system to provide precise and versatile torque regulation. Apart from that, the proposed work includes the enhancement of torque output in a variety of running regions through flux weakening control and the maximum torque per ampere strategy. Based on the simulation results, the optimized multi-rate PI control scheme has good efficiency, decrement in torque ripple, and very excellent system response. The proposed method demonstrates its ability to generate driving performance, conserve energy, and extend operating life of EPMSMs in HEVs.
