Andrew Tridgell 8600ad8d7f AHRS: revert to the old drift correction algorithm
we need to work out why Craigs quad flipped today before we enable
this new drift correction

Andrew Tridgell ce016b5ae8 AHRS: include P term in omega
thanks to Jon for suggesting this

Andrew Tridgell 0fa1f29cf3 AHRS: implement spin rate limits
this follows the method that Bill developed in his fastRotations
paper. We've demonstrated that this is indeed needed in APM, as we
were able to produce the 'dizzy' effects in both the ArduPlane and
ArduCopter simulator

Andrew Tridgell 3ffecc18d8 AHRS: cope with copters with no compass
if a copter doesn't have a compass, we can't use the GPS for gyro
drift correction

Andrew Tridgell 69512ea0ea Rover: a rover moves along its X axis

Andrew Tridgell 426006d98f SITL: fixed GPS heading in simulated UBlox

Andrew Tridgell 20c1baf585 SITL: changes UBlox simulation to 5Hz

Andrew Tridgell 624fdda89c autotest: switch to full accel modelling in multicopter simulation
the new AHRS code should allow for centripetal compensation in
multicopters

Andrew Tridgell 69e68783d3 ArduTracker: update for new compass interface 2012-06-27 16:01:50 +10:00

Andrew Tridgell 7883c4a545 ACM: ArduCopter updates for new compass interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell 44b7d94b1c APM: ArduPlane updates for new compass interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell d9583ae5eb Compass: remove the need to call calculate() on the compass object
the new AHRS code doesn't use calculate() and the compass.heading
attribute. Instead it works on the raw magnetometer vector. This
change removes the internal calculate state from the compass object
and instead adds calculate_heading() for use by older code that
doesn't go via AHRS.

This significantly reduces the calculation involved in compass updates

The null offsets enable/disable code is also removed, as it is not
needed now that compass offsets are not linked to the AHRS state.

Andrew Tridgell 5370f9c411 AHRS: normalize the ge vector in drift correction, and use barometer
The normalisation ensures the error term scales uniformly with
different accelerations.

The barometer is used for vertical acceleration estimation
2012-06-27 16:01:50 +10:00
Andrew Tridgell 7eb150a2f0 ACM: adapt the ArduCopter code for new barometer interface 2012-06-27 16:01:50 +10:00
Andrew Tridgell 4fda89beb7 APM: update for new barometer interface
the barometer can now calibrate and return altitude values.

A 0.3 low pass filter is used on altitude to match the previous code
2012-06-27 16:01:50 +10:00
Andrew Tridgell 53e950531e Baro: added get_altitude() and get_climb_rate() interfaces
this allows the barometer driver to calibrate and return altitude and
climb rate values. This will be used by the AHRS drift correction code
for vertical velocity

The climb rate uses a 5 point average filter
2012-06-27 16:01:50 +10:00
Andrew Tridgell 9fd3d15026 Filter: added 5 point average float filter 2012-06-27 16:01:50 +10:00
Jonathan Challinger 1ff9461bfb AHRS: brought DCM more inline with Bill's implementation
omega_I applied continuously. _ki larger. Stop integrating when _omega.length()>20

The key change was the scaling of ge to ensure the error is not
quadratic

Andrew Tridgell 4a91c267d7 APM: set_centripetal() is now set_fly_forward()
this controls more than just centripetal correction
2012-06-27 16:01:49 +10:00
Andrew Tridgell d71e82191f ACM: enable GPS in AHRS for ArduCopter
this is an experiment in centripetal correction for multicopters
2012-06-27 16:01:49 +10:00
Andrew Tridgell 73faaddc1b AHRS: first successful version of Bills new drift correction system
This makes 3 major changes:

 1) fixes the scaling of the yaw drift correction term to fix the time
 constant

 2) don't integrate the mag vector over multiple readings

 3) accumulate omega_I changes over 15 seconds before applying, to try
 to prevent omega_I picking up short term responses
