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 c990714377 AP_TECS: added get_max_climbrate() 2014-08-07 09:29:31 +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
Andrew Tridgell 98530928b5 AP_TECS: make target landing speed a float 
some users may want more precise control
 2014-03-20 17:34:36 +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 88b0364fcd AP_TECS : Add protection for airspeed runaway due to pitch errors 2014-03-09 19:59:16 +11:00
Andrew Tridgell 9b8311580b AP_TECS: update for AHRS API change 2014-02-15 05:48:24 +11:00
Paul Riseborough 9bbddb2f66 AP_TECS : Use NavEKF height and height rate data if available 2014-02-15 05:48:21 +11:00
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.

Andrew Tridgell b096881f81 AP_TECS: added time to TECS messages 2013-11-04 21:36:40 +11:00
Andrew Tridgell 28a4b6ad9f AP_TECS: update for AHRS API change 2013-11-04 21:21:42 +11:00
Andrew Tridgell 84336bc74e AP_TECS: added initial flight_stage handling 2013-10-12 13:12:43 +11:00
Andrew Tridgell 16d2ad9796 AP_TECS: changed to AP_Vehicle.h 2013-09-13 11:44:31 +10:00
Andrew Tridgell 3c967a9c71 AP_TECS: use a ahrs reference 
saves a pointer access
 2013-08-14 14:58:49 +10:00
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.

Andrew Tridgell 620d067ee1 AP_TECS: use ahrs EAS2TAS for true airspeed 2013-07-22 12:50:01 +10:00

Paul Riseborough 9c431b4a04 TECS: use altitude supplied by mainline code
