Jonathan Challinger 3faca88423 AC_PosControl: allow control of xy rate constraint behavior 2015-02-06 17:00:48 +09:00
Robert Lefebvre 14d76d158a AC_AttitudeControl: Correct comment. 2015-02-03 14:55:30 +09:00
Randy Mackay 07a0388f25 AC_PosControl: move alt limit to set_alt_target_from_climb_rate
The alt limit is instead enforced when the target is set using the
set_alt_target_from_climb_rate function

priseborough 12ea1d6e85 AC_AttitudeControl: Scale angle demand noise filter
Scales filter frequency using EKF nav gain scaler to take advantage of the reduced nav frequency whichcan tolerate a slower angle response.
This is required to reduce the effect of EKF optical flow noise increase with height.

priseborough e80b1c67cd AC_AttitudeControl: Add EKF optical flow noise gain scaler
Allows gains to be adjusted to compensate for optical flow noise

priseborough 2dff76394d AC_PosControl: Add spike and noise filter to demanded angles
This has been done to provide a smooth psotion hold when using an optical flow aided EKF which can be noisy.

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.
