| 摘 要： | 针对一种主轴砂轮线速度在80 m/s以上的高速精密轧辊磨床,以主轴异步电机YVF160L2和逆变器的数学模型为基础,采用空间电压矢量调制(SVM)与直接转矩控制(DTC)相结合的SVMDTC方案,减少轧辊磨头砂轮主轴运行时的转矩脉动；并利用模型参考自适应器建立了速度观测器,实现高速精密轧辊磨头主轴电机无速度传感的闭环控制。仿真结果表明,基于辨识速度的SVMDTC系统能有效改善主轴电机运行时定子磁链和输出轴转矩的波动,控制性能得到明显提升。

| Abstract: | Based on the mathematical model of the spindle motor YVF160L2 and the inverter, the space voltage vector modulation (SVM) and the direct torque control (DTC) were used for the highspeed precision roll grinder which grinding speed in more than 80 m/s. (SVMDTC), reducing the torque ripple during the operation of the spindle grinding wheel spindle; and using the model reference sensor to establish the speed observer to realize high speed precision roll grinding head spindle motor without speed sensing Closedloop control. The simulation results showed that the SVMDTC system based on the observation speed could effectively improve the fluctuation of the stator flux and output shaft torque during the operation of the spindle motor, and the control performance was improved obviously. |
