| 摘 要： | 在异步电机的矢量控制系统中,转子电阻的变化严重影响着磁链的估算,制约着整个控制系统的运行性能.实时地对转子电阻进行辨识,成为提高整个系统性能的保证.基于模型参考自适应理论,提出一种新的转子电阻辨识算法,利用李雅普洛夫方法证明系统的稳定性.仿真结果表明:该估算算法能准确地辨识转子电阻,并且具有一定的鲁棒性.

| Abstract: | The variation of rotor resistance affects the estimation of flux greatly in vector control system for induction motor,which restricts the operation performance of the system.Real-time identification of the rotor resistance can improve overall system performance.Based on MRAS theory,a new rotor resistance identification algorithm is proposed and the stability of the system is proved by the meaning of Lyapunov.Simulation results show that the method can accurately identify the rotor resistance and has certain... |
