Research on Control System of Superconducting Transformer Excitation Power Based on RBF-PID

Attenuation in the secondary current may occur in superconducting transformer of the superconducting conductor measuring device due to the resistance loss of secondary coil joints. In order to overcome the influence of secondary current reducing and improve output performance of the superconducting transformer, the author of this paper analyzes principles of superconducting transformer, sets up the mathematical model of superconducting transformer, adopts the RBF-PID algorithm to control the excitation power supply of superconducting transformer. By establishing simulation model of superconducting transformer control system in MATLAB/Simulink, results show that compared with traditional PID control system, the RBF-PID control system comes with faster response, smaller over shoot and better robustness.
