Andrew Tridgell	abba6395ad	AP_TECS: fixed spelling error	10 years ago
Andrew Tridgell	1552278fa3	AP_TECS: use aparm.stall_prevention	10 years ago
Andrew Tridgell	bf591b0008	AP_TECS: take load factor into account in min airspeed ... this will push up minimum airspeed when turning	10 years ago
Andrew Tridgell	2b48434e60	AP_TECS: fixed throttle demand on underspeed ... thanks to Philipp Oettershagen for finding this bug!	10 years ago
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.	10 years ago
Andrew Tridgell	b495905da5	AP_TECS: fixed some warnings	10 years ago
Andrew Tridgell	a6ca11facf	AP_TECS: allow zero throttle in flare for landing	11 years ago
Andrew Tridgell	6c1eed0a20	AP_TECS: bring in flare sink rate more slowly ... this should reduce pitch overshoot in the flare	11 years ago
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	11 years ago
Andrew Tridgell	500e20b08d	AP_TECS: make TECS aware of LAND_PITCH_CD ... this makes the flare a bit smoother	11 years ago
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	11 years ago
Andrew Tridgell	2297c6bcd2	AP_TECS: added TECS_LAND_SINK parameter ... this controls the sink rate for the final stage of landing	11 years ago
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	11 years ago
Andrew Tridgell	e24febec1b	AP_TECS: avoid a valgrind bug	11 years ago
Michael Day	312a2fc8dc	AP_TECS: Parameter TECS_LAND_SPDWGT allows custom landing speed weight.	11 years ago
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	11 years ago
Michael Day	bd7e1b82e1	AP_TECS: Auto landing now takes throttle_nudge into account.	11 years ago
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.	11 years ago
Paul Riseborough	88b0364fcd	AP_TECS : Add protection for airspeed runaway due to pitch errors	11 years ago
Andrew Tridgell	9b8311580b	AP_TECS: update for AHRS API change	11 years ago
Paul Riseborough	9bbddb2f66	AP_TECS : Use NavEKF height and height rate data if available	11 years ago
Paul Riseborough	bc311542ab	AP_TECS : Fixed bug preventing accel launch detection when not using AS sensor	11 years ago
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.	11 years ago
Andrew Tridgell	b096881f81	AP_TECS: added time to TECS messages	11 years ago
Andrew Tridgell	28a4b6ad9f	AP_TECS: update for AHRS API change	11 years ago
Andrew Tridgell	84336bc74e	AP_TECS: added initial flight_stage handling	11 years ago
Andrew Tridgell	3c967a9c71	AP_TECS: use a ahrs reference ... saves a pointer access	12 years ago
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.	12 years ago
Andrew Tridgell	620d067ee1	AP_TECS: use ahrs EAS2TAS for true airspeed	12 years ago
Andrew Tridgell	fb0e48a25d	AP_TECS: adapt for new airspeed variable names	12 years ago
Paul Riseborough	66d60953df	TECS: added height update_pitch call	12 years ago
Paul Riseborough	2c5db9a165	TECS: added support for throttle nudging	12 years ago
Paul Riseborough	9c431b4a04	TECS: use altitude supplied by mainline code ... this allows for use of ALT_OFFSET and ALT_MIX	12 years ago
Paul Riseborough	a694b781c7	AP_TECS: Add non airspeed sensor pitch to throttle mode lost during integration	12 years ago
Andrew Tridgell	87f6cc715d	AP_TECS: fixed parameter doc formatting	12 years ago
Paul Riseborough	8082122053	TECS-WIP : Fixed bug in initialisation of DT value	12 years ago
Andrew Tridgell	904e6b5b8f	AP_TECS: for _DT to at most 0.1	12 years ago
Andrew Tridgell	68232a10f9	AP_TECS: updates to use new aircraft parameter structure	12 years ago
