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 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 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

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

Andrew Tridgell df6013616e AP_Math: added rotmat <-> euler functions

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

Andrew Tridgell 8190204287 AP_Math: added safe_sqrt() function
this function will never return NAN. It will return zero for negative
numbers.

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.

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

Andrew Tridgell 8707965c15 DCM: changed the sense of floating point range comparison
This allows us to detect NaN, otherwise NaN values were considered 
'in range'

Andrew Tridgell 9caa4aeb44 DCM: range check the matrix before calculating pitch
The asin() in the pitch calculation can only take values between -1
and 1. This change ensures that the value is in range, and if it isn't
then we force a normalization. If that fails we reset the matrix

Andrew Tridgell 13693e1a04 DCM: reset more values on renorm blowup
when DCM blows up, we need to reset a lot more variables to ensure
that any NaN values don't persist

Andrew Tridgell b231112957 DCM: renorm_sqrt_count is now called renorm_range_count 2012-02-23 08:16:08 +11:00
Andrew Tridgell 5cfe1ad5dc DCM: remove the taylor expansion optimisation for renormalisation
The sqrt() costs about 44usec on a 2560, which is small enough for us
not to worry about the speed.

This also changes the range of values where we declare a blowup to
much less likely, which means we can cope with larger delta_t glitches
