Initial position estimation strategy for a surface permanent magnet synchronous motor used in hybrid Article

Bing TIAN,Qun-tao AN,Li SUN,Dong-yang SUN,Jian-dong DUAN

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 8,   Pages 803-813 doi: 10.1631/FITEE.1500298

Abstract: nonlinear model for surface permanent magnet synchronous motors (SPMSMs) is adopted to estimate the initialrotor position for hybrid electric vehicles (HEVs).Usually, the accuracy of initial rotor position estimation for SPMSMs relies on magnetic saturation.polarity is roughly identified with the aid of the saturation evaluation function, based on which an estimationof the position is performed.

Resource evaluation，position and distribution of tight sandstone gas in China

Zhang Guosheng ,Deng Songtao

Strategic Study of CAE 2012, Volume 14, Issue 6,   Pages 87-93

Abstract:

Based on the reservoir forming condition research of tight sandstone gas in Ordos Basin, Sichuan Basin and Tarim Basin, the authors give two types of tight sandstone gas reservoirs,sloped lithologic type and structural type which are the main of tight sandstone gas reservoir. The favorable gas region is predicted with multi-factor overlay method. And based on the existed tight sandstone gas reservoir analysis, the authors get the main parameters such as reservoir abundance, gas-bearing area coefficient which are necessary for gas resource calculation of the large basin through analogism method. According to the result of this resource evaluation, the tight sandstone gas geological recoverable resource in China is 9.2×1012～13.4×1012 m3 which is widely distributed over coal measure basins. The tight sandstone gas is the most realistic source in present. Due to the support of government policies and the motivation of technological progress, it might become one of the pillar sources in natural gas development in 10 to 20 years.
