| 摘 要： | 直接转矩控制（DTC）在交流电机驱动系统中是一种较完善的控制理论。事实证明它能很容易的应用到无位置开关磁阻电机的驱动中。这种控制方案包含一个改进的电机线圈和一个简单的驱动电路,在驱动电路中电压矢量的应用形式和交流电机驱动系统类似。该控制方案的关键就是直接磁链补偿,它无需利用传感器和磁场曲线就可以精确的判断出转子的位置。

| Abstract: | Direct torque control is a well established control principle for any AC motor drive system. Facts have proved that the DTC technique could provide a simple solution to the drive of a switched reluctance motor with no position-sensor. This control scheme consists of a modified motor winding and a simple drive circuit, in which the voltage vector is utilised in a mode similar to that of an AC drive. A key part of the control embraces a direct flux compensation,which can make an accureate estimate of a rotor position without the use of magnetisation curves or sensore. |
