74eef7018a Quaternion: added an AP_Quaternion library

367947fd33 HWSTATUS: if we don't know the voltage, report it as zero 
this will tell us if board_voltage() is really working
 2012-03-10 10:34:28 +11:00
Andrew Tridgell
64cc04ae09 ACM: adjust yaw drift correction constants

Andrew Tridgell
511f65e2ef APM: fixed reset of control switch when short_fs_action is disabled

6ba6e11e7b DCM: added a small amount of accel smoothing to update_DCM_fast() 2012-03-10 10:34:27 +11:00

3b1782f369 DCM: don't use the z accel sensor for drift correction 
the z accel is the noisest, and seems to do more harm than good. Using
just x and y is sufficient for drift correction by assuming the vector
length
 2012-03-10 10:34:27 +11:00
Andrew Tridgell
4031320f7c DCM: added a small amount of gyro and accel smoothing 
possibly not needed, but convenient to be able to test with different
values

cc8278c1ac DCM: got rid of _error_roll_pitch from object state 
this can be a local error variable in common with the yaw code. This
saves 12 bytes in the object.

c8e9d57567 temp remove filter for quad motors during testing. It's unlikely this filter did anything at all to be honest. 2012-03-06 22:23:06 -08:00

730476fdfd ACM - 
Implemented automatic ranging of Alt Hold gains. Works well in simulator and testing.
- alt hold estimation moved to 50 hz
- simple fixed observer calc for smooth and accurate climb rates useful for derivative calcs
- auto-reset of the I term by moving I value into throttle value. This recalcs the gain every 20seconds for battery drainage compensation in long flights.
- remove filtering for Nav_throttle
- added a way to lower the gain on nav_throttle for descents by / climb_rate error by 2 - seems to work OK and keeps copter from dropping like a rock when the Baro drifts quickly lower.
- removed old throttle hold set point code
- made throttle override for alt hold +- 200 vs 250
