Satellite formation-keeping about libration points in the presence of system uncertainties (2016)
Presentation / Conference Contribution

This paper studies a control law to stabilize the orbital motion in the vicinity of an unstable equilibrium points and periodic orbits in the circular-restricted three-body problem. Utilizing the eigenstructure of the system, the fuel efficient forma... Read More about Satellite formation-keeping about libration points in the presence of system uncertainties.

Trajectory design using the center manifold theory in the circular restricted three-body problem (2016)
Journal Article

Lagrangian points are libration points in the circular restricted three-body problem. Three of them are collinear libration points,
and known to have unstable periodic and quasi-periodic orbits in the vicinity of themselves. This study aims to desig... Read More about Trajectory design using the center manifold theory in the circular restricted three-body problem.

Design of sliding mode controllers for formation flying along unstable periodic orbits in CR3BP (2015)
Presentation / Conference Contribution

Recently formation flying along halo orbits near a libration point or simply formation flying in the vicinity of a libration point of the circular-restricted three-body problem (CR3BP) has been studied from the point of view of future missions such a...

Design procedure of chattering attenuation sliding mode attitude control of a satellite system (2014)
Presentation / Conference Contribution

This study presents a design procedure for a new robust nonlinear control algorithm based on the theory of the terminal sliding mode (TSM) to control the attitude of a satellite system. Since the traditional TSM controllers include a discontinuous fu... Read More about Design procedure of chattering attenuation sliding mode attitude control of a satellite system.

New Continuous Sliding Mode Design for Spacecraft Attitude Control (2014)
Presentation / Conference Contribution

New Chattering Attenuation Sliding Mode Control of a Flexible Spacecraft (2014)
Journal Article

An improved sliding mode control (SMC) strategy for the attitude control problem of a nonlinear spacecraft with an elastic appendage is investigated. Since conventional sliding mode controllers include a discontinuous function, a significant problem... Read More about New Chattering Attenuation Sliding Mode Control of a Flexible Spacecraft.

Sliding mode control of a microsatellite attitude (2010)
Presentation / Conference Contribution

Attitude control of a micro-satellite is analyzed with sliding control method. With this method, attitude dynamics of satellite is robust against uncertainties and unknown disturbances. Nonlinear and coupled model in this paper is utilized and to pre... Read More about Sliding mode control of a microsatellite attitude.
