Ovarian epithelial cancer is a gynecological tumor with a high risk of recurrence and death. In the clinical diagnosis of ovarian epithelial cancer, CA125 has become an important indicator of disease burden. To account for patient recurrence and death, a proper method is needed to integrate information from biomarkers and recurrence simultaneously. In the past 10 years, many methods have been proposed...
In the paper, an innovated radial-axial hybrid magnetic bearing (HMB) is proposed, which is driven by a 2-phase AC power inverter in radial directions and a DC amplifier in axial direction respectively. The axial and radial biased magnetic fluxes are provided by a common radial polarized permanent magnet ring, and the axial and radial control magnetic fluxes are provided by the inner and outer two-layer...
A dynamic decoupling control approach based on neural network inverse system theory is developed for the AC-DC 3 degrees of freedom hybrid magnetic bearing (AC-DC 3-DOF HMB), which is a multivariable, nonlinear, strong coupled system. The configuration of AC-DC 3-DOF HMB is introduced briefly. The mathematics equations of radial and axial suspension forces are deduced. The analytical inverse system...
