DOI: 10.1016/j.ijleo.2017.04.057
Abstract: Abstract A hybrid fuzzy-PID controller scheme is proposed to maintain line of sight (LOS) stabilize against carriers’ disturbances and achieve a higher tracking precision. The control model is established based on two-axis and two-frame utilizing… read more here.
