The characterization of the interior-permanent-magnet synchronous machine (IPMSM) is limited due to the nonlinearity of the flux-linkage profile by using the conventional motor model. A nonlinear flux-linkage model for the IPMSM with 12 coefficients is proposed in this paper. It can generally be used to estimate the real d-axis flux linkage, q-axis flux linkage, maximum-torque-per-ampere (MTPA) locus,...
In the development environment of the Microsoft Visual Studio.Net, the C# development language, SQL SERVER 2000 database development tool and the idea of modularization design are adopted to develop the network design system of bearings based on ASP (application service provider) model. The system can be used to introduce the performance characteristics and application, inquire the information of...
The effect of surface resistivity of high voltage provider on the space dispersion of induced charge of RPC has been studied experimentally. The result of experimental measurement shows that two-Gaussian function can be used to fit the dispersion of induced charge of RPC. The Gaussian function with narrower width is mainly due to the expansion of avalanche charge in the gas gap of RPC and the Gaussian...
The influence of the width of integrated FADC time window on the position resolution of a RPC has been studied experimentally and theoretically. The results of theoretical calculation and experimental measurement have shown a good agreement. In this situation 100ns FADC time window can be an optical choice for the position resolution of one incident charge particle.
This paper presents a novel image segmentation method based on the integration of level set and marker methods. The two distinct techniques for image processing are combined in a manner to utilize the strengths of both. The internal markers obtained by extended-maxima transform bring a priori knowledge to bear on the image segmentation. The initial level set function is constructed from region of...
