Identification and Inversion of Magnetic Hysteresis Using LabVIEW and Matlab
نویسندگان
چکیده
The sinusoidal magnetization of a sample material is difficult to achieve, since the magnetic hysteresis poses a strong nonlinearity. In order to find the proper input voltage, a feed-forward strategy with a hysteresis model identification and inversion is proposed. The classical Preisach model in the Everett formulation is used for this purpose and eddy current effects are also included. The control system consists of a laptop computer with a data acquisition card using LabVIEW and MATLAB. The user interface is programmed as virtual instruments. After an initial identification procedure the model, its inverse, and the proper input voltage for a desired sinusoidal magnetization are computed. The resulting application achieves accurate results, is easy to use, supplies the user with transparent and clear information, and adds the flexibility for automation or remote control.

متن کاملTwo-Dimensional Compact Inversion of Magnetic Data in the Presence of Remanent Magnetization
Remnant magnetization causes a change in the direction and intensity of the magnetization vector. If inversion is performed regardless of remnance, in some cases it may have unreliable and misleading results. For inversion with respect to remnant magnetization, several solutions have been proposed so far, one of which is to convert the data of total magnetic field into data that is independent ...
