一种改进的异步电机转子磁场定向校正算法
A Modified Rotor Flux Oriented Correction Algorithm of Induction Motors
摘要
Abstract
The parameters of induction motors are affected by temperature, the field current and so on, which result in oriented deviation in the rotor flux oriented vector control. Although the algorithm based on reactive power can realize oriented correction, the correctional accuracy is affected by the dead zone. Therefore, a modified method which is based on the dot product of the stator current and rotor flux was proposed. A closed-loop system was established based on the model reference adaptive principle. This method is independent of the dead zone when the reference voltage is used instead of the actual voltage to calculate the average value of the adjustable model. Therefore the correctional accuracy was improved. However, the steady accuracy is affected by the excitation inductance. Hence, a simple compensation algorithm was designed. The simulation and experimental results verify the effectiveness of the proposed algorithm.关键词
