新型直线电机支持向量机非线性建模研究

Research on SVM model of a novel cylinder linear motor

以一种新型圆筒直线电机为研究对象,通过建立直线电机的有限元模型及试验验证,获得了直线电机的一种仿真计算方法。在正交试验设计和随机试验设计的基础上,建立了直线电机性能参数的样本空间,采用支持向量机(SVM)回归建模方法,建立了直线电机的非线性数学模型,并将有限元模型和SVM模型进行了比较,证实了SVM模型的可靠性和高效性。

Through establishing the Finite Element ModeI（FEM） of a novel linear motor and testing its prototype, a kind of method used in simulating the character of linear motors was obtained. By means of the method of the orthogonal experimental design and the random experimental design, the sample space of the character parameters of the linear motors was established, and by the nonlinear regression method of the Support Vector Machine （SVM）, the nonlinear mathematic model of a novel linear motor was given. Comparing the FEM model with the SVM model in aspect of consistency and computing speed, the authenticity and effectiveness of the SVM model were confirmed.
