Model predictive control of low earth orbiting spacecraft with magneto-torquers
online resource
posted on 2008-11-17, 14:40 authored by Mark Wood, Wen-Hua Chen, Denis FertinThe problem of attitude control using magnetic
torque rods is addressed, in order to demonstrate predictive
control as a suitable and effective technique of magnetic
attitude control. The study addresses the key issues of magnetic
field modeling, controller stability and implementation. Two
controller designs are implemented, the first adopting an MPC
approach with a constant magnetic field assumption, while the
second method includes the true variation of the magnetic field
within the control law. Both methods demonstrate significantly
improved performance over PD control with the inclusion of
the true magnetic field variation leading to the best results.
Controller stability is considered with and without terminal
penalty within the cost function. Floquet analysis demonstrates
both methods to be stable, however the terminal penalty based
method leads to a more stable controller.
