Global Attitude Estimation using Uncertainty Ellipsoids
Taeyoung Lee, Amit K. Sanyal, Melvin Leok +1
Attitude estimation is often a prerequisite for control of the attitude or orientation of mechanical systems. Current attitude estimation algorithms use coordinate representations…
A Discrete Variational Integrator for Optimal Control Problems on SO(3)
Islam I. Hussein, Melvin Leok, Amit K. Sanyal +1
In this paper we study a discrete variational optimal control problem for the rigid body. The cost to be minimized is the external torque applied to move the rigid body from an ini…
Attitude Maneuvers of a Rigid Spacecraft in a Circular Orbit
Taeyoung Lee, Melvin Leok, N. Harris McClamroch
A global model is presented that can be used to study attitude maneuvers of a rigid spacecraft in a circular orbit about a large central body. The model includes gravity gradient e…
