Instability of fixed, low-thrust drag compensation
, 2003 FORCED drag compensation using continuous low-thrustpropulsion has been considered for satellites in low Earth orbit. This simple, but nonoptimal, scheme merely requires that the thrust vector is directed opposite to the drag vector and that the ...

The reduction of scale force uncertainty in low thrust regions
, 1997 Minimal scale force uncertainty in low thrust regions of an engine’s operating envelope is critical to meet flight test specifications as Air Force requirements become more stringent.

CES Transactions on Electrical Machines and SystemsLinear flux-switching permanent magnet motors (LFSPMs) have been proposed for long stator applications such as rail transit. However, the conventional linear permanent magnet synchronous motor (LPMSM) suffers from thrust ripple, which degrades the motor ...
