带LC滤波器的永磁同步电机多步模型预测电流控制
Multi-Step Model Predictive Current Control of Permanent Magnet Synchronous Motor with LC Filter
摘要
Abstract
[Objective]In order to improve the control performance of model predictive current control(MPCC)for permanent magnet synchronous motor(PMSM),an LC filter was added between the PMSM and the inverter.[Method]A third-order multi-step MPCC system with LC filter was established.Predictive control was applied to the inverter current,capacitor voltage,and motor current,with simulation comparisons made against a first-order multi-step MPCC and field orientation control(FOC).[Results]Comparison results showed that under the same switching frequency and number of prediction steps,the third-order MPCC significantly reduced torque ripple and current ripple in the PMSM compared to the first-order MPCC,while also achieving lower total harmonic distortion(THD)in the current.Additionally,as the number of prediction steps increased in the third-order MPCC,both current THD,current ripple,and torque ripple progressively decreased.[Conclusion]As the number of prediction steps increases,the control performance of the third-order MPCC system gradually improves.The third-order MPCC outperforms the first-order MPCC.At higher switching frequencies,the third-order MPCC with 4-5 prediction steps delivers better control performance than FOC.关键词
