| 摘 要： | 针对永磁同步电机的调速及伺服运行状态具有较强周期性与规律性的特点,提出了基于灰色系统预测理论的电机转子位置和速度自检测方法.通过相关因子序列的灰色关联度分析,确定了转子位置及速度的有效预测因子:即磁链-电流-转子位置角关系曲线及反电势-电压有效值-转子速度关系曲线,转子位置的预测采用等间隔的5条关系曲线,建立了等间隔GM(1,1)预测模型,而转子速度的预测根据低速及中高速范围确定为非等间距的8条关系曲线,建立了非等间隔GM(1,1)预测模型.将此预测方法用于永磁同步电机的矢量控制当中,仿真及实验表明状态估计准确、参数变化鲁棒性强,控制系统具有优良的静态和动态性能. |

| Abstract: | For the fact that the running of permanent magnet synchronous motor(PMSM) has a strong characteristic of periodicity and orderliness,the new rotor position and speed self-sensing technique is proposed using grey system prediction theory.The valid predictors which are the curves of magnetic flux-stator current-rotor position and the curves of electromotive force-virtual value of voltage-rotor speed are chosen by grey correlation analysis.Then the rotor position was predicted by the five curves using equal in... |
