This paper presents an extensive tutorial and a complete review on the state-dependent
Riccati equation (SDRE). The review covers contributions from the beginning to (near the …

This paper introduces an Optimal Fuzzy Sliding Mode (OFSM) controller for the control of
fuel sloshing in a spacecraft during orbital maneuvers. In order to optimize controller's gains …

In this work, a new perturbed dynamical system to describe the satellites relative motion is
derived considering that the gravitational attractive force is generated by the continued …

In this paper, the digital implementation of a continuous-time robust nonlinear optimal
controller is presented as an experimental study with real-time computations. Complicated …

The aim of this paper is attitude control of spacecraft utilizing nonlinear control feedback
linearization. Input-output linearization is a technique of feedback linearization theory. In this …

This paper considers the nonlinear interaction of the rigid body dynamics of a spacecraft
with the sloshing dynamics of the liquid propellant in its partially filled spherical tank during …

Rendezvous is one of the fundamental phases of on-orbit servicing (OOS) missions. Since it
requires high accuracy and safety, modeling is an indispensable part. Therefore, this article …

This paper describes the implementation of fast state-dependent Riccati equation (SDRE)
control algorithms through the use of shallow and deep artificial neural networks (ANN) …

This paper presents Guidance and Control (G&C) systems for multi-satellite assembly in
proximity operations. The systems utilize the twistor model, which is linearized through …

In this study, a model predictive control (MPC) method is developed for a servicer spacecraft
autonomously approaching a tumbling failed spacecraft at an ultraclose range. Flight safety …
