摘要
应用修正的Dahl模型,通过能量积分分批识别出不同电流下的参数,确定参数与电流的关系。提出的参数辨识方法,将含有滞迟环节的非线性参数识别转化为线性识别问题,达到了较高的识别精度。
According to the modified Dahl model,the method of energy integration was given to derive the relationship between applied current and the model parameters.A method for evaluating the model parameters was presented to transfer a nonlinear parameter identification for a hysteretic system to a linear parameter identification and the results showed that the proposed method has high precision.
