A novel parameters estimation strategy of interior permanent magnet synchronous machine (IPMSM) for accurate torque control is proposed and investigated in this paper. The difference of q-axis inductance and d-axis inductance is estimated by a PI regulator using the deviation between actual output power and reference power. The estimated difference of dq inductance can be used to achieve maxim…
In the present study, we used two chloroplast DNA (cpDNA) fragments (trnL‐F and rps16) and the nuclear ribosomal internal transcribed spacer (ITS) sequence data to examine intraspecific differentiation and phylogeographical history of Allium wallichii. Based on wide scale sampling (28 populations and 174 individuals) across the entire distribution range of this species, 33 cpDNA haplotypes a…
In recent years, Chinese cities have attempted to extend urban welfare provisions to migrants, but migrants’ participation in such programs is relatively low. This paper examines migrant welfare participation in Shanghai and its association with personal characteristics, institutional factors, the labor market, attitudes about welfare programs and settlement intention. Except for hukou status…
This article develops a slow–fast loop polytopic linear parameter-varying model and proposes a systematic gainscheduled switching attitude tracking control scheme for a near-space hypersonic vehicle. First, the dynamics of nearspace hypersonic vehicle is modeled as a slow–fast loop polytopic linear parameter-varying model using the Jacobian linearization and tensor-product model transformat…
Abstract. To explore the effects of the novel properties of carbon nanoparticles (CNPs) on cytotoxicity, the adsorption of serum proteins in cell culture medium on multi-walled carbon nanotubes and three kinds of carbon blacks was investigated. The uptake of CNPs by Hela cells was measured quantitatively using 99mTc radionuclide labeling and tracing techniques, and the dependence of CNPs u…
