Abstract: This study describes the implementation of principal component analysis method for electromagnetic drives technological production process control. The analysis of existing methods of technological processes of production of proportional electromagnetic drives is performed. The method for control of technological production process is developed. The approximation of dynamic magnetization characteristic of electromagnetic drives is made. Projecting of dynamic characteristic of the magnetization by method of principal component analysis is implemented. The calibration and classification methods are selected. To separate the training sample into groups and classification of dynamic characteristic of the magnetization for the test sample was used method of formal independent modeling of class analogies. The results of implementation of selected methods are presented.
