Following space discoveries, asteroids were found as rich sources of minerals and organic
matter that can be exploited. In this paper, we present a precise, fast, and robust energy …

This paper presents a novel nonlinear guidance scheme for ground track control of aerial
vehicles. The proposed guidance logic is derived using the sliding mode control technique …

This paper aims at desensitizing the optimal trajectory for landing on the small bodies with
reduced landing error in the presence of initial state error, parameters uncertainties of the …

This paper presents a convex programming algorithm based on modified Rodrigues
parameters for a six-degree-of-freedom asteroid powered landing trajectory design problem …

The detection of small bodies is very important, and studying the gravity fields of small
bodies is a key requirement when designing exploration missions. This paper proposes an …

Successful future asteroid landing missions require that the control method provides
advanced disturbance rejection performance and strong robustness against parameter …

In this paper, a six-degree-of-freedom (6-DOF) control scheme for asteroid landing subject to
collision avoidance and line-of-sight (LOS) constraints is developed within the newly …

In the framework of twistors, a saturated adaptive six-degree-of-freedom (6-DOF) control law
for asteroid landing, which avoids the collision between the spacecraft and asteroid, is …

Future asteroid landing and sample return missions will seek for landing sites with high
scientific value, such as hazardous terrains, which means that the spacecraft needs the …

This study has introduced a predictive framework including a heuristic guidance law named
Predictive Path Planning and Multiple-Horizon Multiple-Model Predictive Control as the …
