摘要
本文分析了感应电动机转子电阻变化对转差型矢量控制系统动、静态性能的影响,提出一种结构简单的转子电阻在线辨识算法,并以8086微处理器构成离散模型参考自适应系统,对转子电阻进行实时校正。实验结果表明,系统能迅速补偿转子电阻的变化,使感应电动机电磁转矩系数基本保持恒定。
The paper analyses the influence of rotor resistance variation on the static and dynamic performance of slip type vector controlled induction motor(?)system.A method on line identifying the rotor resistance variation is proposed based upon model reference adap- tive system.It is implemented in 8086 microprocessor.Experiment result shows the system can quickly compensated the rotor resistance variation and keeps the torque nearly constant.
