This article describes the control of a rotary inverted pendulum utilizing on–off-type cold gas
thrusters as the actuators, which have high similarities with thruster actuated spacecrafts …

Reaction thrusters (RTs) are used as an alternative to momentum exchange devices when
disturbance torques exceed the control authority of momentum exchange devices. The …

In the common practice of designing an attitude tracker for an aerospacecraft, one
transforms the Newton-Euler rotation equations to obtain the dynamic equations of some …

This paper provides new results of the dynamical modeling and controller designing for
autonomous close proximity phase during rendezvous and docking in the presence of …

This paper provides the thruster control approach for micro-satellites to realize autonomous
