purpose : to evaluate the correlation between inner segment/outer segment (is/os) line and external limiting membrane (elm) layer integrity at foveal center and visual outcome and to investigate the prognostic factors in optical coherence tomography (oct) that related to final visual acuity (va) and recovery time in acute central serous chorioretinopathy (csc) methods : we prospectively studied...

This study proposes a generic mathematical modelling and decoupling fault-tolerant vector control for dual three-phase permanent magnet synchronous machine (PMSM) with one phase open based on the conventional voltage source inverters, accounting mutual coupling between two sets of windings second harmonic inductance. When PMSM has open, flux-linkages are asymmetric there components in reference...

This paper establishes the state-space model of cup rotor permanent-magnet doubly fed machine in synchronous reference frame. The feedback-linearization control method is used to realize decoupling flux and torque. Then, upper lower load torque boundaries are solved. Furthermore, minimize stator current magnitude under a certain torque, maximum per ampere (MTPA) derived. Finally, simulation res...

Virtual synchronous generator (VSG) control is based on the fact that line impedance in a microgrid highly inductive. This assumption was made due to emulation of stator winding an electrical machine. concept can affect controllability with complex impedance, generating deviations chosen operation point. To overcome this issue, additional techniques must be implemented. paper describes novel ma...
