摘要
分析了定子电阻的变化对永磁同步电机PMSM直接转矩控制系统性能的影响,提出了一种基于磁链误差的参数自整定PI估计器估计定子电阻的方案。仿真说明,PI电阻估计器能够很好地跟踪定子电阻,提高了PMSM直接转矩控制对参数变化的自适应能力。
Influence of stator resistance variation on the performance of permanent magnet synchronous motor （PMSM） in direct torque control system is analyzed. Then a method for stator resistance estima- tion using a proportional-integral （PI） estimator which has self-adjusting parameters is proposed. Through the simulation, the PI resistance estimator is of good performance in tracking stator resistance, which improves the adaptability to parameters variety of PMSM direct torque control.
