An integral sliding mode control (ISMC) for stator currents of the induction motor (IM) is developed in this work. The proposed controller d-q synchronous reference frame, by using indirect field-oriented (FOC) method. Robust asymptotic tracking current components presence model uncertainties and coupling disturbance terms has been guaranteed an enhanced ISMC surface. More precisely, stationary...

climatological study of the mid-latitude storm tracks was investigated using the daily global forecast system (gfs) and the national centers for environmental prediction (ncep) reanalysis data sets from 1948 to 2008 winter seasons. in anomalous winter 2007-2008, decreasing of eddy kinetic energy along with the reduction of eddy available potential energy upstream of atlantic storm track are rel...

Potentials and limits of the Hybrid-Excitation Permanent-Magnet (HEPM) synchronous machine are dealt with in this paper. A six-pole is taken into consideration, both parallel series configurations analysed compared. Taking advantage rotor excitation coils, permanent magnet (PM) flux can be adjusted according to operating speed improve its performance parameters. The electro-magnetic force first...

El Niño/Southern Oscillation (ENSO) exhibits evident amplitude asymmetry with stronger Niño than La Niña events. Equatorial submesoscale eddies act as an important damper of ENSO via their induced upward heat flux () from the subsurface to surface ocean. Yet effect on remains unexplored. Using a high-resolution global climate simulation, we found that strengthening in Niño3.4 region during is m...

This paper investigates and compares the torque-generating capabilities electromagnetic performance of advanced non-overlapping winding induction machines (AIM), conventional (CIM), interior-permanent magnet (IPM) for electric vehicle (EV) applications. All investigated are designed based on specifications Toyota Prius 2010 IPM machine. The steady-state flux-weakening characteristics calculated...

The variability and trend of volume advective heat flux, in addition to the net inflow outflow flux Java Sea for 64 years (1950–2013), along with its relationship monsoon, ENSO (El Niño Southern Oscillation), IOD (Indian Ocean Dipole), have all been studied. A simulation 3D hydrodynamic HYCOM (HYbrid Coordinate Model) a 1/8° grid resolution was performed this study. Judging from simulated resul...
