% DFF attitude control routine.
This routine implements attitude control for the DFF system. PID controllers
are used for attitude control - momentum control is not used. The torque
command is applied directly in the simulation, without the use of an RWA
model. Provision is made for filters of arbitrary order for loop shaping.
Inputs are the target quaternion and the true quaternion. Small angles are
computed from the two quaternions. The target quaternion should be near the
true quaternion for best results.
If there are no inputs it will perform a self-test.
