摘要
针对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的问题,通过感应电动机参数解析灵敏度分析,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、参数易辨识性的关系。最后提出了一种有效的感应电动机负荷模型综合策略。
In accordance with the problem that some parameters can be identified easily and other parameters cannot be in the load modeling of induction motor, this paper elucidates the relations between the parameter sensitivity and the parameter identifiability through sensitivity analysis. The results show that parameters with high sensitivity are relatively easy to be identified, on the other hand, the parameters with low sensitivity are relatively difficult to be identified. Finally, the effective synthesis strategy of induction motor load model is advanced.
