I am working on the attitude control of a spacecraft with flexibles appendages, but my simulink model return an algebraic loop warning, and I think it could be the reason of the error in the control.
I can run the simulation but the quaternions, after a first moment of correct trend, start a constant oscillation (i link the picture of the trend).
So I reach the right quaternion value but then i start oscillating. All the suggestions are welcome.
I have already tried with a memory block or a delay block to break the loop, but the simulation can't work in this way.
I link also the equations that bring to the algebraic loop.
Thank you for the help!
