DC MOTOR CONTROL SYSTEM WITH OPTIMIZATION OF THE TRANSIENT DURATION

The synthesis of the structure of the automatic control system of direct current motors is carried out, and the methodology of the study of the duration of the transient process during the control of the direct current motor is presented. A study of the influence of the regulator parameters on the duration of the transition process was carried out, which allowed to choose the optimal ones for the criterion of the minimum duration of the transition process

Electromagnetic circuit model of an eddy current defectoscope

A model of a device for nondestructive control by eddy currents has been proposed. The device and the object under control are represented by an equivalent circuit in the form of an electromagnetic circuit described by the system of differential finite equations in the coordinates of loop magnetic fluxes and currents of windings. The model allows us to take into account three parameters of the defects: depth, width, and conductivity. The spline method of analysis of periodic processes is used to carry out calculation.
