不用速度传感器的直接自调整控制

Direct Self-Control of Induction Motors without Speed Sensors

本文对不用任何机械传感器的直接自调整控制进行了研究。该方法可用于动态性能要求不高的工业生产中。首先提出了实际速度计算和速度调节器的设计原理,然后给出了电路原理图,最后给出的实验结果表明,系统具有较好的动态性能和静态精度。

The paper suggest direct self-control of indution motors, which does not use any mechanical transducer.This is devoted to those applications, for which the dyna- mical performances are not be optimized. At first the principles of calculating the exact speed and speed regulator are carried out. Then practical analog devices are described. At last, experimental results are given: the shown performances and static accuracy are good.
