EVALUATION OF THE OPERATING CONDITIONS OF THE EDDY CURRENT DEVICE IN THE DYNAMIC CONTROL MODE

The results of the dynamic eddy current control system are considered. A layout of the system was developed, which allows control of metal samples in dynamic mode. A mathematical model has been developed that describes changes in the information criteria of the response signal depending on the material of the investigated metal objects and the speed of their linear movement relative to the coils of the control system. The research focuses on finding optimal operating speeds of the control system. An integral-differential approach is proposed for determining the maximum information between feedback signals obtained from different metals. The optimal range of scanning speeds has been determined, which allows obtaining the maximum sensitivity of information criteria for various metals, and can be used to build mobile eddy current express control systems.
