Autonomous Attitude Determination and Control System for the Ørsted Satellite
The Ørsted satellite mission imposes comparatively high requirements on autonomy of the attitude control system. Cost requirements, on the other hand, impose simple hardware and cheap actuators in form of magnetorquer coils. These conflicting requirements are fulfilled through development of novel attitude and control algorithms and wide on-board autonomy. The entire control and attitude determ...
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 کاملCoordinate Systems for Attitude Determination and Control
This guideline provides a procedure which specifies and documents consistent, useful, and welldefined coordinate system (or frame) definitions for spacecraft attitude control design and analysis. Several example coordinate frames and transformations are presented to show how these definitions are used to address various Attitude Control System (ACS) design issues. Past experience has shown the ...
متن کاملModeling and Simulation of Control Actuation System
In this paper a dynamic simulation model is implemented using Fuzzy logic controlled Brushless direct current motor drives for fin control actuation. The Brushless direct current (BLDC) motor is modeled using MATLABSIMULINK models and controlled by fuzzy logic controller. In addition to this, current hysterias controller block, inverter block and speed estimated block, entire blocks are modeled...
متن کاملIntegrated GNSS Attitude Determination and Positioning for Direct Geo-Referencing
Direct geo-referencing is an efficient methodology for the fast acquisition of 3D spatial data. It requires the fusion of spatial data acquisition sensors with navigation sensors, such as Global Navigation Satellite System (GNSS) receivers. In this contribution, we consider an integrated GNSS navigation system to provide estimates of the position and attitude (orientation) of a 3D laser scanner...
