摘要
文章分析了感应电机无速度传感器控制中在同步转速为零且带负载状态下自适应磁链观测器(A FO)观测状态和估计转速的渐进稳定性。设计了基于模型参考自适应系统 (MRAS)全速域渐近稳定的状态观测和转速估计算法 。
In this paper we fist analyze the stability of rotor speed estimation and rotor observation with adaptive flux observer in the speed sensor less control of induction motors.After that,based on the model reference adaptive systems we propose a new estimating algorithm of rotor speed.With this algorithm the system is stable for any operation states.Simulation results show that new algorithm is efficient.
