灵敏度小的 meaning in Chinese

sluggish

Abstract : in accordance with the problem that some parameters can be identified easily and other parameters are difficult to be identified in the load modeling of three order induction motor , this paper elucidates the relations between the parameter sensitivity and the parameter identifiability through sensitivity analysis . the problem that deals with the effects on parameter sensitivity of the intensity of excitation is also studied . finally , the parameter identification strategy that is meaningful and valuable in modeling is advanced
文摘:三阶感应电动机负荷模型中部分参数易辨识，且辨识结果稳定，而另一部分参数难辨识，辨识结果存在较大离散性.通过对参数灵敏度进行分析，指出了参数灵敏度与参数易辨识性之间的关系，以及扰动强度与参数灵敏度从而参数易辨识性的关系.最后给出了对实际三阶感应电动机参数辨识的分步方法：利用较小的扰动强度数据来辨识具有较大灵敏度的参数；利用具有足够强度的扰动数据来辩识灵敏度小的参数
