Randy Mackay 4f0b26bd48 AP_L1_Control: update_waypoint gets dist_min argument
L1_dist can become extremely short for slow moving vehicles leading to unnecessarily jerk turns after passing waypoints.  This reduces the minimum length along the track that the vehicle will point.

Andrew Tridgell 31092da426 AP_L1_Control: removed create() method for objects
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

Tom Pittenger 25c3367341 AP_L1 - add a stale flag
threading bug fix. When a mission wp updates, but the L1 controller had not yet, the data is stale. Example, On Plane when NAV_LAND starts for a moment your xtrack and bearing is most likely bear zero regardless if you have a big turn or not until 10 Hz later when the update() gets called and updates those values with correct values for the new waypoint.

Jonathan Challinger f0f5239d8f AP_L1_Control: use set_default for runtime param defaults 2015-10-26 11:15:54 +11:00
Tom Pittenger 695efb8df3 AP_L1_Control: added integrator to help xtrack error converge to zero
new param: NAVL1_XTRACK_I
    // @Description: Crosstrack error integrator gain. This gain is applied to the crosstrack error to ensure it converges to zero. Set to zero to disable. Smaller values converge slower, higher values will cause crosstrack error oscillation.
fixes https://github.com/diydrones/ardupilot/issues/2650

when param is changed the integrator is set to zero. This makes for easier tuning by seeing it converge to zero on each change.

Gustavo Jose de Sousa 4278bfcec5 AP_L1_Control: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Andrew Tridgell 571c48b9d5 L1_Control: cleanup some unused code and variables 2013-04-15 10:52:32 +10:00
Brandon Jones a3c2851120 AP_L1_Control: Addition of library for geometry calculations required for L1 Control.
1) Explicit control of tracking loop period and damping which removes previous
   variation in period with speed and fixed damping ratio
2) Explicit control of track capture angle (now set to 45 degrees by default)
3) Removal of restriction on loiter radius being greater than L1 distance

The circle(loiter) control is a L1 and PD hybrid utilising L1 for waypoint capture and PD control for circle tracking.
