Andrew Tridgell b6ecce8329 AP_TECS: 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

Tom Pittenger 063f517424 Plane, TECS, AP_Landing: rename stage LAND_ABORT to ABORT_LAND 
this will reduce confusion when searching for FLIGHT_LAND_* and you get a bunch of takeoff related hits. It will also make more sense when the landing library fully manages the FLIGHT_LAND stage entirely because it will not mange FLIGHT_LAND_ABORT

Murilo Belluzzo d8b58690ad AP_TECS: Remove useless 'if' statement 
This should fix CID 91386.

Before removing the 'if', I checked the log to confirm that both branch
didn't end-up being equal by mistake in some commit. But it looks like
the file was added in the project this way.

Andrew Tridgell d3d2ce3e0d AP_TECS: use full throttle in initial takeoff 
during the first part of a takeoff when we have not yet reached the
target airspeed this forces the throttle to maximum. This fixes a case
where the throttle may drop too low during the first part of takeoff
and lead to a stall.

Tom Pittenger 595badce3e AP_TECS: rely on single flag for all land stage differences 
recent fixes in Plane have made the stage more accurate so exceptions/hacks are no longer needed to differentiate between knowing if executing NAV_LAND vs being in stage_approach.

Andrew Tridgell b4c6a0e30e AP_TECS: added logging of speed_weight and state flags 2016-03-26 08:41:09 +11:00
Andrew Tridgell 8ff932b61c AP_TECS: allow underspeed to end faster 
we now can exit an underspeed condition if we stay above min speed for
3 seconds and also reach 15% above min speed. This prevents a problem
with the thrust line causing downpitch leading to a crash due to too
much throttle

Tom Pittenger a85d4f2f4b AP_TECS: reverse-thrust cleanup 
- throttle slew rate was using % full range including the negative range (-100 to +100 instead of 0 to 100) which meant it was faster
- throttle integrator windup limit was higher than normal because it's a porportional to throttle max - min but that makes no sense when min is negative causing larger limits

Tom Pittenger 67e2db7975 AP_TECS: add TECS_LAND_PDAMP 
// @Description: This is the damping gain for the pitch demand loop. Increase to add damping  to correct for oscillations in speed and height. If set to 0 then TECS_PTCH_DAMP will be used instead.

Tom Pittenger a139789693 AP_TECS: add TECS_LAND_TDAMP for land damp 
+     // @Description: This is the damping gain for the throttle demand loop during and auto-landing. Same as TECS_THR_DAMP but only in effect during an auto-land. Increase to add damping to correct for oscillations in speed and height. When set to 0 landing throttle damp is controlled by TECS_THR_DAMP.

Tom Pittenger 67ce22660e AP_TECS: 1/3 new param TECS_LAND_SRC for Land Sink Rate Change 
// @Description: When zero, the flare sink rate (TECS_LAND_SINK) is a fixed sink demand. With this enabled the flare sinkrate will increase/decrease the flare sink demand as you get further beyond the LAND waypoint. Has no effect before the waypoint. This value is added to TECS_LAND_SINK proportional to distance traveled after wp. With an increasing sink rate you can still land in a given distance if you're traveling too fast and cruise passed the land point. A positive value will force the plane to land sooner proportional to distance passed land point. A negative number will tell the plane to slowly climb allowing for a pitched-up stall landing. Recommend 0.2 as initial value.

Tom Pittenger 5ba2bff85f AP_TECS: Reverse Thrust 
Reverse thrust for controlled landings, even with much steeper approach slopes. This is achieved by allowing throttle demand to go negative to maintain a target airspeed. A Pre-Flare stage was added, triggered by an altitude, to allow for a slower airspeed just before land. That lower airspeed can be near stall.

Lucas De Marchi 2591261af6 Global: rename min and max macros to uppercase 
The problem with using min() and max() is that they conflict with some
C++ headers. Name the macros in uppercase instead. We may go case by

    git grep -l -z PROGMEM | xargs -0 sed -i 's/PROGMEM//g'

Andrew Tridgell 36432e6515 AP_TECS: use climb rate filter consistently between DCM and EKF 
we should use baro height not hgt_afe for the climb rate filter. This

Gustavo Jose de Sousa 1fbbe3ed81 AP_TECS: 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.

priseborough e2d47f836e AP_TECS: Fix bug causing plane to fly high on landing approach 
The introduction of the height rate flare logic caused the demanded height rate to be zero except when a flare manouevre was being performed. This caused the plane to lag behind height changes if the D gain was non-zero, which caused it to fly high during landing approach.
