Caio Marcelo de Oliveira Filho c70dda526c AP_TECS: use millis/micros/panic functions 2015-11-20 12:34:46 +09:00
Lucas De Marchi 831d8acca5 Remove use of PROGMEM 
Now variables don't have to be declared with PROGMEM anymore, so remove
them. This was automated with:

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

The 2 commands were done so we don't leave behind spurious spaces.

AVR-specific places were not changed.

Andrew Tridgell 094b9cb35e AP_TECS: reformat using astyle 2015-09-16 14:24:45 +10:00
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
makes the climb rate consistent with the one from the EKF. The lidar
correction comes in with the demanded height, not the observed height

Tom Pittenger 46a83c7ae9 AP_TECS: added flight stage FLIGHT_LAND_ABORT 
- do what TAKEOFF does in tecs, push the throttle up

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.

Peter Barker 457f77314e AP_TECS: use 64-bit timestamps for dataflash logs 2015-05-27 11:54:16 +10:00
Andrew Tridgell cf4602afc1 AP_TECS: fix for HAL_SITL rename 2015-05-05 09:45:56 +10:00
Michael du Breuil 04e9141881 AP_TECS: Allow tecs to control throttle during takeoff 2015-04-16 08:56:37 +10:00
Andrew Tridgell 5a4ed85588 AP_TECS: added TECS_LAND_PMAX 
this limits maximum pitch during the flare, which both reduces
integrator windup and prevents too high pitch which can cause a stall
 2015-03-19 14:46:41 +11:00
Andrew Tridgell 569626ac1a AP_TECS: fixed APM2 build 2015-03-16 08:40:18 +11:00
Andrew Tridgell 060f553097 AP_TECS: provide a much smoother transition before flare 
this moves the pitch constraint smoothly between unconstrained and
fully constrained over two time constants before the flare. This
greatly reduces the sudden pitch changes at flare

Andrew Tridgell 4e5510c99e AP_TECS: fixed warning 2015-01-01 15:14:48 +11:00
Andrew Tridgell 597273cfff AP_TECS: remove lag from height demand in landing 
this predicts ahead the height demand for landing, where we have a
continuous demanded descent. This removes the effect of the lag
introduced by the height demand filters

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.

priseborough 053c5054f3 AP_TECS: Change default landing damp gain to 0.5 2014-11-29 20:03:49 +11:00

Andrew Tridgell bf591b0008 AP_TECS: take load factor into account in min airspeed 
this will push up minimum airspeed when turning
 2014-11-12 13:36:02 +11:00
Andrew Tridgell 2b48434e60 AP_TECS: fixed throttle demand on underspeed 
thanks to Philipp Oettershagen for finding this bug!

priseborough d6508acfa5 AP_TECS : Prevent throttle undershoot after climb 
If the plane was unable to achieve the climb and got significantly below the internal TECS demanded climb profile, the the PD term would be a large value at the top of climb, and would take some time to reduce due to the rate limiter. This meant that the integrator state could be pushed to a very low value and effectively cause the throttle to sit on the lower limit for longer than desired after levelling out.

Andrew Tridgell b495905da5 AP_TECS: fixed some warnings 2014-10-22 18:27:18 +11:00
Andrew Tridgell a6ca11facf AP_TECS: allow zero throttle in flare for landing 2014-08-30 05:14:57 +10:00
Andrew Tridgell 6c1eed0a20 AP_TECS: bring in flare sink rate more slowly 
this should reduce pitch overshoot in the flare
 2014-08-30 05:13:18 +10:00
Andrew Tridgell 7547cd45f5 AP_TECS: bring the flare height rate demand in slowly 
bring it in over 0.5s to give less of a bounce
 2014-08-27 20:13:01 +10:00
Andrew Tridgell 500e20b08d AP_TECS: make TECS aware of LAND_PITCH_CD 
this makes the flare a bit smoother
 2014-08-27 20:11:48 +10:00
Andrew Tridgell 68dd61c7c7 AP_TECS: added TECS_LAND_TCONST 
this allows control of the time constant for landing in TECS. A lower
time constant gives tighter altitude control on landing approach
 2014-08-27 17:14:19 +10:00
Andrew Tridgell 2297c6bcd2 AP_TECS: added TECS_LAND_SINK parameter 
this controls the sink rate for the final stage of landing
 2014-08-13 21:38:05 +10:00
Andrew Tridgell 7c4d31c481 AP_TECS: added TECS_PITCH_MAX and TECS_PITCH_MIN 
this allows the TECS controlled pitch limits to be smaller than the
FBWA limits. It is common for a human pilot to want a bit more
discretion over pitch than you want the automatic controller to use

Andrew Tridgell e24febec1b AP_TECS: avoid a valgrind bug 2014-07-14 09:44:35 +10:00
Michael Day 312a2fc8dc AP_TECS: Parameter TECS_LAND_SPDWGT allows custom landing speed weight. 2014-04-10 15:42:49 +10:00
Andrew Tridgell a55c4e2296 AP_TECS: set target airspeed, not min/max airspeed, on landing 
this seems to prevent ballooning of the altitude when we are in the
landing approach, and gives a much smoother landing
 2014-03-20 17:34:39 +11:00
Michael Day bd7e1b82e1 AP_TECS: Auto landing now takes throttle_nudge into account. 2014-03-20 17:34:26 +11:00
Michael Day 861690dea2 AP_TECS: New params LAND_ARSPD and LAND_THR auto-slowing landings. 
Also controlling pitch by ignoring height error during landing.
This serves to keep the nose up.

Paul Riseborough bc311542ab AP_TECS : Fixed bug preventing accel launch detection when not using AS sensor 2014-02-07 19:20:54 +11:00
Paul Riseborough 585d61b960 AP_TECS : Reduce tendency to overspeed during climbout 
The old code relies on the action of the integrator to raise the nose above the minimum pitch angle which depending on the model and the tuning can be too slow to correct. Biasing the pitch angle to climbout minimum will reduce the taken before an overspeed condition is corrected.

Paul Riseborough 34f0af25cc AP_TECS : Improvements and bug fixes to feed-forward throttle demand 
This fixes a bug in the feed-forward throttle that prevented the bank to throttle compensation from working properly during descents.
It also adds bank to throttle compensation to the non-airspeed sensor throttle algorithm.
