Field oriented control (FOC) and direct torque control (DTC), also called vector control, are most famous control methods in high-performance motor applications. If we want to specify the basic handicaps of both methods: the FOC has parameter dependence while the DTC has high torque ripples. This paper proposes a new adaptive bandwidth approach to reduce torque ripples in DTC controlled inducti...
The prevalence of the blood-borne TT virus (TTV) in Italian hemophiliacs treated with different preparations of factor VIII was determined. Of the 178 hemophilic patients (mean age, 29 years), TTV-DNA was found in 123 (69%), in comparison to 22 of 100 (22%) blood donors (P <.0001). Of the 123 patients who tested positive for TTV, significant numbers were also infected with human hepatitis virus...
Little is known about the natural history and the pathogenicity of the TT virus (TTV). We present our findings of a cross-sectional study based on the TTV DNA screening of 173 multiple-transfused patients and a longitudinal study based on the follow-up of TTV DNA-positive patients. Overall, 48 patients (27.7%) tested positive for TTV DNA. The influence of the number of blood donor exposures on ...
A variety of techniques exist for reducing the cogging torque of conventional radial flux PM machines. This paper presents an application of two cogging torque minimization techniques in which the permanent magnets are skewed in a conventional manner and the stator slots are closed with soft magnetic composite material. The comparative analysis of the different motor designs regarding the coggi...
