for Synchronous Motors
1997Co-Authors: S. Di Gennaro, L JlAbstract:In this paper the problem of tracking asymptotically a given angular velocity reference is formulated for a synchronous motor, when the angular velocity is supposed to be not available for measuring, and the rotor Resistance Varies during the operation. An output feedback dynamic controller which solves the problem is hence determined and tested by simulations.

Adrenergic control of vascular Resistance Varies in muscles composed of different fiber types: influence of the vascular endothelium
American journal of physiology. Regulatory integrative and comparative physiology, 2011Co-Authors: Bradley J. Behnke, Robert B. Armstrong, Micheal D. DelpAbstract:The influence of the sympathetic nervous system (SNS) upon vascular Resistance is more profound in muscles comprised predominately of low-oxidative type IIB vs. high-oxidative type I fiber types.

An Improved Speed Identification Method Based on MRAS
2007Co-Authors: Nian Xiao-hongAbstract:Because the voltage model involved pure integrator,which caused initial value and drift problems.These problems and Resistance Varies effected the precision of speed identification.An improved method was presented,which used high-pass filter to avoid these problems and adapted the cut-off frequency on-line to improve dynamic performance by using fuzzy controller;and then eliminated the influence of stator Resistance Varies by using fuzzy controller to estimate and adapt stator Resistance on-line.Simulation results indicated that the method had the characteristic of good dynamic and static performance and high precision speed identification.

An Improved Speed Identification Method Based on MRAS
2007 Chinese Control Conference, 2006Co-Authors: Huang Zhiwu, Yang Tongguang, Gui Wei-hua, Shan Yong-teng, Nian Xiao-hongAbstract:Speed identification is crucial in speed sensorless induction motor drives. Because the voltage model involves pure integrator, which will cause initial value and drift problems. These problems and Resistance Varies effect the precision of speed identification. This paper presents an improved method, which uses high-pass filter to avoid these problems and adapt the cut-off frequency on-line to improve dynamic performance by using fuzzy controller; and then eliminate the influence of stator Resistance Varies by using fuzzy controller to estimate and adapt stator Resistance on-line. Simulation results indicate that the method has the characteristic of good dynamic and static performance and high precision speed identification.

nanostructure and local properties of oxide layers grown on stainless steel in simulated pressurized water reactor environment
Corrosion Science, 2014Co-Authors: Toni Massoud, Vince Maurice, Lorena H Klei, Antoine Seyeu, Philippe MarcusAbstract:Abstract The morphology and local electrical Resistance of duplex oxide films formed on 316L stainless steel at 325 °C in simulated primary coolant of pressurized water reactor have been investigated at the nanometre scale with Conductive Atomic Force Microscopy. The electrical Resistance Varies over ∼1 order of magnitude for most oxide grains and over 2–3 orders of magnitude locally at grains and grain boundaries. This is rationalized in terms of local variation of the composition and thus resistivity of the mixed Fe(II)–Cr(III) barrier inner layer of the oxide films with grain boundaries of the outer layer possibly promoting Cr(III) enrichment.
