Attitude Control of LISA Pathfinder Spacecraft with Micro-Newton FEEP Thrusters under Multiple Failures

Attitude and orbit control systems for the LISA Pathfinder mission

“…The 3-axis control strategy, together with other potential measures, such as to implement control in body axes instead of the prime axes, to enter into de-spin submode earlier, etc. have been investigated, with very promising results, as reported in the reference paper [7]. Thus new control strategy and controller tunings are also adopted for the MSAM based on colloidal thrusters.…”
