Novel Adaptive Controller for Effective Magnetic Measurement Under Arbitrary Magnetization

Résumé

Abstract—In the context of the ever-expanding application of soft magnetic materials, the fully controlled magnetic measurement has, therefore, become essential. It ensures not only the accurate modeling of materials but also the rigorous quality control throughout the manufacturing process, as well as the explicit communication of magnetic data in academic studies or between suppliers and customers. Due to the non-linearity and hysteresis nature of electrical steels, automatic flux density controller is required for high standard measurements. We propose in this paper a novel steady-state digital control algorithm with two loops, one to regulate amplitude and the other to correct waveform of the flux density. Measurement results for various samples tested by Epstein frame and ring specimens under different waveforms, a wide range of frequency and high amplitudes of the flux density have proven the high adaptability, accuracy and convergence speed of this controller. Its principle is discussed in details, together with the employed measurement bench.
