Jason Short e4e8189448 added a simple rest of nav_throttle just in case 2012-02-25 13:31:21 -08:00
Jason Short cd55498a5c increased speed of alt hold I term based on Jani's Logs 2012-02-25 13:31:21 -08:00
Jason Short a3f65b4a23 increased the rate error for more responsive alt hold 2012-02-25 13:31:21 -08:00
Jason Short 68739f3cc4 Based on Jani's latest logs I've made two tweaks to alt hold.
The first is to remove the filter on the throttle output for alt_hold.

The second was to open up the constraint on climb rate. This is to deal with larger than expected disturbances causing altitude changes.

Andrew Tridgell bd2776aedd Compass: use constructor to set initial values for _learn and _use_for_yaw
this ensures they are set if you have MAG_ENABLE==0
2012-02-25 17:36:31 +11:00
Andrew Tridgell 56bb74ef36 DCM: disable compass null offsets when setting initial yaw
we need to ensure the compass null offsets code doesn't see a sudden
yaw change, or it will change the offsets by a large amount very
suddenly

Andrew Tridgell 6b265c5034 ACM: use a NULL gps pointer in DCM init
current DCM API does need a GPS reference passed in, but it can be
NULL
2012-02-25 15:08:49 +11:00
Andrew Tridgell f50f4357ca Compass: catch the case of a user enabling a compass mid-flight
if a compass has not been initialised at startup we can't enable it
mid-flight, as we don't have the orientation
2012-02-25 14:51:09 +11:00
Andrew Tridgell 3fe5b3151b allow MAG_ENABLE to be changed in flight
this disables the compass in DCM if MAG_ENABLE is changed in
flight. Without this we would use a fixed yaw once the compass is
disabled

This also makes sure we don't pass the compass to DCM till we have
done a read. This ensures we have a good compass fix for the initial
DCM heading

Andrew Tridgell 3abe035557 DCM: use the new use_for_yaw() compass method 2012-02-25 14:51:09 +11:00
Andrew Tridgell c3319afadd Compass: added COMPASS_LEARN and COMPASS_USE parameters
these allow you to control if the compass should be used for yaw and
if it should learn its offsets. This is useful for locking in compass
offsets once they are confirmed to be good, and for learning offsets
without using them in flights.

The default is to behave the same as previously, which is
COMPASS_LEARN=1 and COMPASS_USE=1
2012-02-25 14:51:08 +11:00
Andrew Tridgell d1f655beee ACM: check the return of compass.init()
if the compass fails to initialise then don't pass it to DCM, or we
will get no yaw control. Report the init failure to the user.
2012-02-25 14:51:08 +11:00
Andrew Tridgell ce5c7c2c85 ACM: don't pass a gps pointer to DCM
after discussion with Randy, we don't want ArduCopter to fall back to
GPS for yaw when the compass becomes unhealthy. So we shouldn't pass
the gps object to the DCM code at all.

Andrew Tridgell 051bd78b37 AP_Param: added some comments on AP_Vector3f handling 2012-02-25 11:37:20 +11:00
Andrew Tridgell 3cf0eebac8 DCM: don't reset _have_initial_yaw for GPS heading unless very slow
wait till we reach 1m/s before we reset _have_initial_yaw. This
prevents us continually resetting the DCM matrix if our ground speed
is close to 3m/s.

Andrew Tridgell 42528e9c33 test: updated VARTest for new AP_Param vector3f handling 2012-02-25 11:37:20 +11:00
Andrew Tridgell 17718720b1 GCS: force scalar type in copy_name()
this enables access to compass offsets over MAVLink
2012-02-25 11:37:20 +11:00
Andrew Tridgell 007a6b8958 AP_Param: added special handling for Vector3f
We would like to be able to use Vector3f as a parameter while exposing
the individual elements of the vector as MAVLink parameters. This
change to AP_Param makes that possible, by giving AP_Vector3f a dual
personality

Andrew Tridgell 1d95137b71 SITL: added -C option to desktop mode
this allows running APM to stdout, which is useful for test sketches

Andrew Tridgell c63ca9c697 DCM: tidy up use of error_course and in_motion
in_motion is not a good name now it is also used for the compass

The error_course and heading component values don't need to be part of
the DCM object, they can be on the stack to reduce the memory usage a bit
2012-02-25 11:37:20 +11:00
Andrew Tridgell d5b619218c DCM: use rotation_matrix_from_euler() to calculate initial yaw
When we first get a compass reading or we first start motion we need
to setup the DCM matrix with the right yaw. This uses
rotation_matrix_from_euler() to get a DCM matrix corresponding to our
current roll/pitch, but with the correct yaw

Andrew Tridgell 48cad8bc25 DCM: use rotation_matrix_from_euler() in matrix reset
this makes the code a bit easier to read
2012-02-24 11:54:11 +11:00
Andrew Tridgell 5009679617 DCM: use calculate_euler_angles() to get eulers from DCM
this makes the code a bit easier to understand
2012-02-24 11:52:55 +11:00
Andrew Tridgell df6013616e AP_Math: added rotmat <-> euler functions
these will make the dcm matrix manipulation easier to understand
2012-02-24 11:52:55 +11:00
Andrew Tridgell 4edf311865 ACM: ensure update_trig() doesn't cause NAN values for cos_roll/cos_pitch
the DCM matrix could have a value over 1.0 for c.x due to rounding
errors
2012-02-24 11:52:55 +11:00
Andrew Tridgell 50f85835bd Compass: ensure we don't produce NAN values for compass heading
this leaves the previous heading values alone if we are at a pitch of
exactly 90 or -90, at which point we can't compute a meaningful
heading
2012-02-24 11:52:55 +11:00
Andrew Tridgell 8190204287 AP_Math: added safe_sqrt() function
this function will never return NAN. It will return zero for negative
numbers.
2012-02-24 11:52:55 +11:00
Andrew Tridgell 0acea11152 DCM: tidy up the nan checking in DCM
use is_nan() on the matrix rather than just on c.x, and add
safe_asin() to the (unused) OUTPUTMODE==2 code.
2012-02-24 11:52:55 +11:00
Andrew Tridgell b4c8d6491a DCM: added matrix recovery on reset
when we get a bad DCM error we can recover a matrix corresponding to
the current attitude, making it more likely that the aircraft will be
able to recover
2012-02-24 11:52:55 +11:00
Andrew Tridgell 1a32ececb4 AP_Math: added a safe_asin() function
this adds range checking to asin()
