Design of Control System for Dynamic Calibration Device of Eddy Current Sensor Based on FPGA

Abstract

In the dissertation, an automatic and integrated calibration device for the static characteristics of eddy current sensors was researched aimed at the great demand of improving the efficiency of calibrating eddy current sensors. The design proposal for the control system in the slave computer of automatic and integrated calibration device for the dynamic characteristics of eddy current sensors was studied. The control method of vibration level automatic adjustment was proposed. A signal generator, a data acquisition unit and a data storage unit were designed. Besides, the serial communication module was also designed to communicate with the master computer.
