| 摘 要： | 在自抗扰技术的基础上建立了磁链的闭环扩张状态观测器模型。该模型不用对系统进行参数辨识就可以抑制内部参数摄动和外部干扰的影响,因此该观测模型有更强的鲁棒性。文中对比了模型参考自适应的速度估算方法,在所提出的转子磁链观测模型的基础上,利用李亚普诺夫稳定定律推得了速度观测自适应律。

| Abstract: | This paper presents a closed-loop rotor flux observer based on the extended state observer(ESO) of active disturbance rejection control(ADRC) technology.The model can inhibit the influence of motor parameter perturbations and external disturbances without any parameter identification,so it has stronger robustness and fast response.Comparing with the speed estimation method of the model reference adaptive system(MRAS),a speed estimation adaptive law is derived through Lyapunov stability theory based on the proposed flux observer. |
