Andrew Tridgell 698749dd92 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 f10097a6d5 AP_Param: added some comments on AP_Vector3f handling 2012-02-25 11:37:20 +11:00
Andrew Tridgell 5e2fbdb6cf 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 690dc9052a GCS: force scalar type in copy_name()

Andrew Tridgell 2e9105c68a 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 55e33c3359 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 ab8cc3d478 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 ddeda1c367 DCM: use rotation_matrix_from_euler() in matrix reset
this makes the code a bit easier to read

Andrew Tridgell 06f37aad75 DCM: use calculate_euler_angles() to get eulers from DCM
this makes the code a bit easier to understand

Andrew Tridgell 16ed8bc8f6 AP_Math: added rotmat <-> euler functions

Andrew Tridgell 1cd3172954 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 c354879f1f 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 17d16bc8c6 AP_Math: added safe_sqrt() function
this function will never return NAN. It will return zero for negative
numbers.

Andrew Tridgell bad653f230 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 c8e6d03c67 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 ef90f336d3 DCM: changed the sense of floating point range comparison
This allows us to detect NaN, otherwise NaN values were considered 
'in range'

Andrew Tridgell 57ffd00b69 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 2bb58db3f7 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 95ef9206dc DCM: renorm_sqrt_count is now called renorm_range_count 2012-02-23 08:16:08 +11:00
Andrew Tridgell 156d98cb9f 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
