Adaptive Control of Mini Space Robot Based on Linear Separation of Inertial Parameters

Aerospace, 2023
Space robots exhibit a strong dynamic coupling between the manipulator and the base spacecraft, with this phenomenon being particularly pronounced in mini space robots.

CONTROLLING ATTITUDES

Pacific Philosophical Quarterly, 2006
Abstract:  I hope to show that, although belief is subject to two quite robust forms of agency, “believing at will” is impossible; one cannot believe in the way one ordinarily acts. Further, the same is true of intention: although intention is subject to two quite robust forms of agency, the features of belief that render believing less than voluntary ...

Time Optimal Attitude Control for a Rigid Body [PDF]

, 2007
A time optimal attitude control problem is studied for the dynamics of a rigid body. The objective is to minimize the time to rotate the rigid body to a desired attitude and angular velocity while subject to constraints on the control input.

Prescribed Performance Fault-Tolerant Attitude Tracking Control for UAV with Actuator Faults

Drones
This paper proposes a prescribed performance fault-tolerant control based on a fixed-time extended state observer (FXTESO) for a carrier-based unmanned aerial vehicle (UAV). First, the attitude motion model of the UAV is introduced.
