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.

Andrew Chapman 048767e389 GCS_MAVLink: camera feedback mavlink messages 
CAMERA_EVENT and CAMERA_FEEDBACK messages, and a couple of enums they
use (CAMERA_EVENT_TYPES and CAMERA_FEEDBACK_FLAGS)

Adjusted some types and added more explicit descriptions of units as
suggested on the call last week.

I will add camera parameter list/get/set functionality as suggested
using the existing parameter mechanism and component IDs rather than
the new CAMERA_INFO messages I had proposed.

pair programmed with Craig Elder
 2014-06-17 14:11:36 +10:00
Randy Mackay 0c9a496262 AC_AttControlHeli: add ATC_RATE_FF_ENAB parameter 
Because this class inherits from AC_AttitudeControl library this new
parameter must be added here as well
 2014-06-10 21:25:33 +09:00
Randy Mackay 46f25c52a4 AC_AttControl: allow enabling/disabling feedforward and accel limiting 2014-06-10 20:03:02 +09:00
Randy Mackay a2f54fdf2c AC_WPNav: smooth waypoint by freezing feed-forward and allowing overshoot 
First part of this fix is freezing the position controller's xy-axis
feed foward as we transition to the new segment.
Second part is work-around for straight line segments in that we allow
the target point to actually overshoot the end of the segment by up to
2m if the segment is a "fast waypoint".  Ideally we would instead notice
the waypoint has been completed and take any left over time or distance
and move our target along the track towards the next waypoint but that
would require a much larger change to allow the wpnav lib to hold the
next two waypoints.
 2014-06-10 20:03:01 +09:00
Randy Mackay ce85d1f6b2 AC_WPNav: use curr pos target as spline origin 
We only use the current target position as origin if the waypoint
controller is active (i..e has been used in the past 1 second).  This is
consistent with how we initialise straight line waypoints
 2014-06-10 20:02:59 +09:00

Randy Mackay 02b4b21f67 AC_AttControl: disable feed forward by default 
Can be re-enabled by setting ATC_RATE_FF_ENAB parameter to 1
 2014-06-10 20:02:55 +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.
 2014-06-10 20:02:54 +09:00

Randy Mackay 5209598459 AC_AttControl: rename init_targets to relax_bf_rate_controller 2014-06-10 20:02:27 +09:00
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.

Randy Mackay 915dad2da4 AC_Circle: use fast_atan2 to calc bearing from center 
This does not save much time because it's only called at initialisation
 2014-06-06 18:51:09 +09:00

Loiter is only a horizontal position controller so it should not set the

Ju1ien aed5787c1b AC_WPNav: bug fix for loiter init in Hybrid 
AC_PosControl::init_xy_controller() has been added to PosControl and is
called by init_loiter_target.
Hybrid is currently using set_loiter_target function to init the loiter
controller. So we have to call init_xy_controller() by set_loiter_target
function.
What happens otherwise?
In AC_PosControl::update_xy_controller, we update "now" with
now = hal.scheduler->millis();
and, as _last_update_xy_ms has not been updated previously by
init_xy_controller(), we just call init_xy_controller().
So, _dt_xy  will be negative and used anyways in all the functions and
PID called by update_xy_controller.
That will avoid at least _accel_target.x/y to be set to 0 but I'm not
sure for the high values, probably an I_term that is not reset and
reached very high value.
Or maybe a cast error somewhere... no clue at all

priseborough 925c5751bd AP_NavEKF: Add ability to inhibit in-flight mag cal and clean up moding 
This will enable in-flight magnetometer calibration to be inhibited unconditionally,
This is required for long balloon carriage flights where ground speed can be high
enough to put it into in-air state, but with very poor observability of magnetic field
states causing bad state estimates and heading offsets to develop over time.

The covariance matrix no longer has rows and columns artificially zeroed when in static
mode. Instead booleans indicating whether wind or magentic field state estimation is
active are used to:

a) Set the process noise on these states to zero to stop their variances from increasing
unchecked when not being updated, and
b) Turn off updates for these states when measurement fusion is being performed.

This reduces the likelihood of a badly conditioned covariance matrix forming
during static mode operation.

A filter divergence check has also been added that will declare the filter unhealthy if
position, velocity and magnetic field observations are all failing their innovation
consistency checks. This unhealthy status will persist for 10 seconds after the
condition clears.

priseborough d745dc2b6f AP_NavEKF : Increased position gate default to reduce impact of accel errors 
Flight testing with windup turns has shown that the position gate threshold
can be tripped with good GPS data causing position jerks. This increases the
initial GPS glitch rejection threshold to effectively 5m when using the
default POSNE_NOISE value of 0.5m.

priseborough 188bea6bab AP_NavEKF : Enable calc of wind velocity when not using airspeed sensing 
This patch also cleans up the logic associated with use of the synthetic
sideslip measurement so that it can never be used for a non fly-forward
vehicle type

This patch adds functionality that initialises the wind-speed vector to the
reciprocal of the ground speed vector, and scaled to 6 m/s. On average this gives
a better initial wind velocity estimate on launch by assuming:

a) launch will be into wind
b) wind speed is equal to global average

It also helps prevent a headwind causing initial underestimation of airspeed
causing high autopilot gains and limit cycles on climb-out, until first
turn when the EKF is able to estimate the wind.
