Fully magnetic attitude control for spacecraft subject to gravity gradient
This paper presents stability and control analysis of a satellite on a near polar orbit subject to the gravity torque. The satellite is actuated by a set of mutually perpendicular coils. The concept is that interaction between the Earth's magnetic "eld and a magnetic "eld generated by the coils results in a mechanical torque used for attitude corrections. Magnetic actuation due to its simplicit...
متن کاملThree-axis Satellite Attitude Control Based on Magnetic Torquing
Magnetic torquing is attractive for generation of control torques on small satellites. The concept is that interaction between the Earth's magnetic eld and a magnetic eld generated by a set of coils in the satellite is used for actuation. This principle is inherently nonlinear, and diicult to use because control torques can only be generated perpendicular to the geomagnetic eld vector. So far, ...
متن کاملThree-axis Satellite Attitude Control Based on Magnetic Torquing
Magnetic torquing is attractive as a control principle on small satellites. The actuation principle is to use the interaction between the earth's magnetic eld and magnetic eld generated by a coil set in the satellite. This control principle is inherently nonlinear, and diicult to use because control torques can only be generated perpendicular to the geomagnetic eld vector. This has been a serio...
متن کاملMagnetic Torquer Attitude Control via Asymptotic Periodic Linear Quadratic Regulation
A method of using magnetic torque rods to do 3axis spacecraft attitude control has been developed. The goal of this system is to achieve a nadir pointing accuracy on the order of 0.1 to 1.0 deg without the need for thrusters or wheels. The open-loop system is under-actuated because magnetic torque rods cannot torque about the local magnetic field direction. This direction moves in space as the ...
متن کاملDynamic Modeling for Earth – Pointing Satellites to Control the Three – axis Attitude without the Attitude Information of One Axis
Various methods are presented to control the attitude of satellite due to lack of information of yaw axis attitude so far. In this paper, a new method is used which is more general and is applicable to all types of satellites, with at least one controller. This method is not limited to YAW axis and can control the two other axes as well. One feature of this approach is the ability to be modi...
