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
 2019-10-26 18:05:17 +11:00
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

Michael du Breuil ca65b214af AP_TECS: Include needed AP_Baro.h 2019-06-27 14:56:21 +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.

Andrew Tridgell 6898ec5776 AP_TECS: prevent airspeed demand spikes causing large pitch changes 
a short term spike in the derivative of speed demand could cause the
constraint on the pitch integrator to push the pitch integrator to
very low values, causing a sharp nose down which takes a long time to
recover from

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
