Performance analysis of low-speed and large-thrust cylindrical linear motor with double-layer fractional-slot winding [PDF]
MATEC Web of Conferences, 2021 For low-speed and large-thrust situations, the single-layer winding permanent magnet linear motor is inefficient because of its large distance, and the thrust fluctuation is large.

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2018 We study the problem of determining time-optimal control of in-plane rendezvous transfer of spacecraft with low transversal thrust. We use the Pontryagin maximum principle to determine the optimal control program.
