  This study describes the algorithm and the results of the practical implementation of the method of process control proportional electromagnetic actuators to control their production process. method algorithm includes four items: the measurement of the dynamic characteristics of the magnetization of the electromagnetic actuator, reduction of the space dimension of input data using the selected projection method, carrying out the classification into groups of measured characteristics, determining the numerical values of the deviations from the norm of defective products with the selected method of calibration. This approach allows us to determine the type and degree of impairment of the mode of the process that will lead to effective management of the production process electromagnetic actuators.

  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.

  The study describes a method of complex predict diagnosis of electromagnetic actuators based on their magnetic flux-current characteristics. Principle Component Analyses (PCA) is used as a diagnostic algorithm, it allows to reduce the source data dimension. Particular defect of the electromagnetic actuator is assessed by accumulation of points in a certain region of space. To predict possible failures of investigated actuators regression model is used.

  The positioning system is developed in which the distributed magnetizing coil made up of a number of small size coils. The mode of impulse magnetization of active elements from Magnetic Shape Memory Alloys (MSMA) is applied with a possibility of magnetic field intensity regulation on the elements. Such approach also allows to realize discrete control mode of MSMA strain and to increase positioning accuracy. The mathematical model for strain assessment of an active element considering permanent strain, nonlinear dependence of strain on the enclosed magnetic field and unevenness of magnetization of an active element is developed. The example of strain modeling of an active element of positioning system is given. Using the mathematical modeling of the three-dimensional electromagnetic field assessment of vortex currents influence on dynamic processes in active elements is carried out which allows assessing its influence on speed of system positioning. Duration of current impulses in the magnetizing coil is determined. The received results allow solving research problems of properties and use of MSMA in creation of high-speed high-precision positioning systems.
