Randy Mackay 82ed70b25e AC_PosControl: add xyz velocity controller 
Velocity controller interpretsthe velocity requests as
desired velocities (i.e. feed forward).  These are then used to update
the target position and also added to the target velocity.
Also renamed the set_desired_velocity() function to
set_desired_velocity_xy() to make clear only lat and lon axis are
updated.
 2014-07-06 17:01:02 +09:00

Randy Mackay b57c0dabf6 AC_AttControl: check accel_rp_max instead of rate_bff_ff_enabled 
We use the accel_rp_max, accel_y_max to check whether to apply accel
limiting or not.  This is related to separate from the
body-frame-feed-forward.

lthall 1bdde31f6b Copter: Fix zero throttle flip issue Stabilize 
The problem is that the init_targets is intended to ensure the
controller doesn't build up the I term when the throttle is low. Because
it is poorly named (or used) it have been written to do something else.
Here I change it to do what the code is trying to use it to do.
