recommendations! Published in 2019 at "International Journal of Fuzzy Systems"

DOI: 10.1007/s40815-018-0566-4

Abstract: This paper studies the station-keeping control of underactuated stratospheric airships in the presence of model uncertainties and wind field, and a T–S fuzzy model-based adaptive backstepping SMC (sliding mode controller) is proposed. Firstly, a fuzzy… read more here.

DOI: 10.1016/j.actaastro.2018.12.002

Abstract: Abstract There are many different types of (quasi)periodic orbits in the vicinity of collinear libration points. These libration point orbits (LPOs) are inherently unstable and must be controlled. This paper studies general station-keeping strategies that… read more here.

DOI: 10.1016/j.ifacol.2017.08.1264

Abstract: In this paper, a control scheme is elaborated to perform the station keeping of a geostationary satellite equipped with electric propulsion. The use of electric thrusters imposes to take into account some additional mutually exclusive… read more here.

DOI: 10.1109/tro.2018.2791600

Abstract: Online approximation of the optimal station-keeping strategy for a marine craft subject to an irrotational current is considered. An approximate policy that minimizes a user-defined cost function over an infinite time horizon is obtained using… read more here.
