阶部分 meaning in English
exponent part
Examples
- 3 . the modeling method based on mechanism analysis and identification method always exits unmodeled high - order part and the modeling method based on neural networks usually has not good enough generalization capability . we fuse above two kinds of modeling method and put forward a hybrid modeling method based on mechanism analysis , identification and rbf neural networks . this paper proposed a hybr id modeling method based on mechanism analysis , identification and rbf neural networks . first , get a object ' s low - order model by the mechanism analysis and identification method . second , adopt rbf neural networks modeling method to compensate unmodeled high - order model . the sum of the low - order model and high - order model is the hybrid model . this kind of hybrid model has more accuracy than a model based on mechanism analysis and identification and has more generalization capability than a model based on neural networks
针对基于机理分析和辨识的建模方法总是存在未建模的高阶部分，精度不够高和神经网络建模方法泛化能力差的缺点，将这两种建模方法进行融合，提出基于机理分析、系统辨识和rbf神经网络的混合建模方法，首先采用机理分析和辨识的方法得到工业对象的低阶模型，再用rbf神经网络建模方法补偿未建模高阶模型，这样得到的混合模型，比单纯基于机理分析和辨识的建模方法具有更高的精度，比单纯的神经网络的建模方法具有更好的泛化能力。
