摘要
提出一个基于磁通观察器的感应电机无速度传感器矢量控制系统。根据感应电机矢量控制理论 ,我们利用 q轴磁通收敛于零实现转速推算。本系统的优点是系统简单 ,并且避免了利用电压模型所引起的问题。
This paper presents a speed sensorless vector contr ol system for induction motors, which is based on a flux observer. According to v ector control theory of IM, we utilize the q-axis rotor flux converging on zero for speed estimation. The advantages of the proposed system are simplicity and avoidance of the problems caused by using only a voltage model. The effectivenes s of the proposed system has been verified by experimentation.
