Performance optimization of free-space optical communication protocols based on results from FSO demonstrations [PDF]
, 2007 The mobile free-space optical channel mainly suffers from relatively long link outages, produced by short-term blockings of the line-of-sight (obstacles, clouds), pointing- and tracking-errors or deep signal-fades caused by index of refraction turbulence

Track‐to‐track association algorithm for passive multisensor system based on trajectory parameter
IET Radar, Sonar & Navigation, 2021 Asynchronous sampling and the ghost point are significant issues in the track‐to‐track association (TTTA) for passive multisensor system. A TTTA algorithm is proposed based on a trajectory parameter to address these issues.

ASMADO‐based refined anti‐disturbance low‐speed control of PMSM
IET Power Electronics, 2023 Permanent magnet synchronous motors (PMSMs) have expectant low‐speed servo performance. However, complex nonlinear disturbances restrict the performance and lead to speed fluctuations, especially for small inertia PMSMs where the current‐loop cannot be ...
