Sliding mode control for attitude maneuvers of Helianthus solar sail

open access: yesActa Astronautica, 2022
The recent successes of demonstration missions based on solar sail technology have paved the way for designing new mission scenarios with propellantless propulsion systems. In this context, the Italian Space Agency has been supporting a preliminary study of Helianthus, an innovative concept of deep-space mission, which is designed to use a solar sail ...

Analysis of Factors Influencing Ship's Maneuvering Times [PDF]

open access: yes, 2023
Ship maneuvering is like a musical piece where many internal and external factors must be managed simultaneously in a synchronized manner. While the prolongation of the maneuvering time increases hydrocarbon emission and operating costs, its acceleration

Stochastic optimization of a chain sliding mode controller for the mobile robot maneuvering [PDF]

open access: yes2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011
In this study we present a chain sliding mode controller for the control of a four wheeled autonomous mobile robot performing aggressive turning maneuver to 90 degrees on a slippery surface. The controller consists of a set of local sliding mode controllers and the hyperplanes of switching between them.
