摘要
为提高控制系统的鲁棒性和稳定性，抑制电机参数变化的影响，本文比较几种作为参考模型的转子磁链算法，提出基于电流反馈估算转子磁链的观测器算法作为参考模型，利用模型参考自适应在线辨识转速，对无速度传感器的直接转矩控制调速系统的性能进行了全面的分析。
In order to improve robustness and stability of the control system,and restrain the influence of the variation of induction motor parameters,after comparing several rotor flux linkage algorithms,we propose the rotor flux estimator algorithm based on electric current feedback estimate as a reference model.Then,using the model referencead aptive system for on line identfication of speed of an induction motor,we give a thorongh analysis of the performance of the direct self control system without velocity sensor
