THE field of trajectory optimization has a rich history dating back to 1950s. Traditionally,
these problems are solved by direct and indirect methods with their advantages and …

Solutions to practical optimal control problems (OCPs) may consist of control profiles that
switch between control limits or assume values interior to their admissible set, either due to …

This paper is devoted to investigating the fault-tolerant reduced-attitude control problem for
boresight reorientation of an uncertain spacecraft subject to pointing and angular velocity …

In this paper, a novel fault-tolerant attitude control synthesis is carried out for a flexible
spacecraft subject to actuator faults and uncertain inertia parameters. Based on the sliding …

This paper proposes a rapid attitude trajectory generation method for satellite reorientation,
which is suitable for both rest-to-rest and track-to-track maneuvers. The problem is first …

This paper deals with the problem of spacecraft time-optimal reorientation maneuvers under
boundaries and path constraints. The minimum time solution with keep-out constraints is …

Free-flying robotic spacecraft play a significant role in the space industry today. Unlike
ground-based robots, the manipulator motion in a space robot can cause undesirable …

Time efficient attitude maneuver for a flexible satellite containing a main rigid body with
some flexible appendages is studied in this paper. For the rigid body, an ideal braking curve …

Time-optimal spacecraft slewing maneuvers with path constraints are difficult to compute
even with direct methods. This paper examines the use of a hybrid, two-stage approach, in …

In order to improve the convergence rate of standard sliding mode controller, time efficient
controllers based on Bang–Bang logic for satellite attitude stabilization and tracking control …
