摘要
该无速度传感器感应电机速度估算方法基于模型参考自适应控制理论,从感应电机的数学模型出发进行了理论推导,介绍了采用这种方法作为转速微调的恒压频比实验系统。最后通过实验验证了这种方案可在不增加系统成本的基础上大大改善系统的速度控制精度。
The method of induction, motor speed estimation without rotational transducers in this paper is based on the model reference adaptive control theory and derived from the mathematic model of the induction motor. We also introduce the constant V/f experiment system which adopts the above method to acquire the expected speed. Then the experiment result has proved that this method can improve the speed control accuracy without adding the system cost.
