Andrew Tridgell a789bb372b AP_TECS: added get_max_sinkrate() API 2021-06-05 13:05:30 +10:00
Samuel Tabor 684ee11fc3 AP_TECS: Add flags to indicate gliding flight, and use these with AP_Soaring. 2020-04-08 09:11:54 +10:00
Samuel Tabor 247738518e AP_TECS: Add a feed-forward term from adjusted demanded airspeed to nav pitch. 2020-04-08 09:11:54 +10:00
Samuel Tabor a27c99fab9 AP_TECS: Return the adjusted demanded airspeed. The aspd_error mavlink message now shows the rate-limited airspeed. 2020-04-08 09:11:54 +10:00
Andrew Tridgell 176d3c0b2f AP_TECS: added reset() method 
used at end of VTOL takeoff

Andrew Tridgell a415423975 AP_TECS: removed TECS_LAND_PMIN 
thanks to TunaLobster for pointing out that it is redundent
 2019-11-19 07:50:40 +11:00
Andrew Tridgell 3e72538f07 AP_TECS: added TECS_LAND_PMIN for min pitch in flare 
this is useful to narrow the range of available pitch after flare

Andrew Tridgell 4f243aca02 AP_TECS: prevent rapid changing of pitch limits on landing approach 
when on landing approach we estimate time to flare based on two noisy
numbers, the vertical speed and height above ground. With noisy
rangefinders this can change rapidly, which resulted in the pitch
limit changing rapidly, leading to a porpoising movement

this limits the rate of change, and also prevents it coming down once
it has nosed up due to pending flare on approach

Andrew Tridgell 587aa33617 AP_TECS: added TECS_OPTIONS 
used for full-time glider

Peter Barker c0f25a96fb AP_TECS: move include of logger to .cpp file 2019-07-09 10:57:20 +10:00
Andrew Tridgell c3545be8a1 AP_TECS: fixed a bug in changes from rate-limited to non-limited airspeed 
The calculation of the non-limited airspeed rate demand used the last
non-limited airspeed, whereas it should have used the last adjusted
value. This led to a single frame spike in airspeed demand, which fed
through to a sudden change in pitch integrator.

Peter Barker b47733142f GLOBAL: rename DataFlash_Class to AP_Logger 2019-01-18 18:08:20 +11:00
Andrew Tridgell f3336fdb60 AP_TECS: removed dependency on soaring controller 2018-07-30 13:09:15 +10:00
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

Lucas De Marchi 61a629d766 AP_TECS: add static create method 2017-09-26 03:01:21 +01:00

Tom Pittenger 84e11fd899 Plane, AP_TECS: do not pass auto_land flag to TECS, it already knows it 2016-12-30 23:50:03 -08:00
Tom Pittenger 8019cedf5b AP_Vehicle,AP_SpdHgtControl,AP_TECS: move enum FlightStages to AP_Vehicle::FixedWing 2016-12-30 23:50:02 -08:00
Tom Pittenger b614b41d6d AP_TECS: fixed compiler warning 
- AP_Landing _landing was declared out-of-order

Tom Pittenger 9035dcbbc5 AP_TECS: migrate aparm "LAND_" params from plane to AP_Landing 2016-11-25 19:07:30 -08:00
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.
 2016-10-24 09:42:01 -02:00
Andrew Tridgell 1171b33419 AP_TECS: added TECS_SYNAIRSPEED parameter 
this allows for the synthetic airspeed estimate to be used in TECS
 2016-10-20 13:22:39 +11:00
Andrew Tridgell 2fab15dcd5 AP_TECS: added use_synthetic_airspeed() API 
used by quadplane during transitions

Tom Pittenger c090ba2257 Airspeed: store reference in libraries and populate it 
- also had to move the initial definition in plane.h so it happened before the others.

Tom Pittenger 7be15be185 AP_TECS: slew the hgt_lag_filter when starting a land 2016-07-19 17:19:10 -07:00
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.

Andrew Tridgell c52451b01b AP_TECS: rename some variables to make them clearer 2016-05-14 08:26:09 +10:00
Andrew Tridgell e698d1f47e AP_TECS: use 64 bit micros 
prevent possible wrap if TECS is not run for a long time
 2016-05-14 08:26:09 +10:00
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.

Tom Pittenger 525c7b24e3 AP_TECS: created accessor for TECS_LAND_ARSPD param 2016-04-21 21:30:48 -07:00
Michael du Breuil fd51c3cc16 AP_TECS: Remove hgt_afe from update_50hz() 2016-04-21 17:03:00 +10:00
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

Lucas De Marchi 9271e97c0b AP_TECS: replace header guard with pragma once 2016-03-16 18:40:43 +11:00
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.
 2016-03-02 10:54:21 -08:00
Tom Pittenger fcb802cccc AP_TECS: add TECS_LAND_I_GAIN and TECS_TKOFF_I_GAIN 
// more integral gain options for land
 2016-03-02 10:54:20 -08:00
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.
