为解决无速度传感器感应电动机矢量控制系统的速度估计问题,以模型参考自适应的理论为基础,利用感应电压矢量进行转速估计并进行仿真,转速估计结果理想,仿真实验所得到的波形与理论分析结果是一致的。并且使相应的无速度传感器矢量控制系统具有良好的静、动态性能。证明了采用模型参考自适应系统,利用感应电压矢量进行转速估计方法的正确性和可行性。

In order to solve the speed estimation problems of speed sensorless vector-controlled induction motordrives, based on the paper MRAS identification theory,by the use of the voltage vector induction to estimates the motor speed,the results of the motor speed estimates is effective and the simulation experiment is consistent,therefore,the proposed MRAS based on speed sensorless vector-controlled induction motor drives have good performance in stady-state and transientstate operation. It shows the MRAS and the voltage vector induction are feasibility and the correctness.
