Note: the author name was removed because this file has almost no
resemblence with the code written by that author 4 years ago, has been
copied to new places, and was initially commited without author anyway.
Also, my opinion is that the version control system should take care of
attribution, and not outdated comments.
* ekf_control: Inhibit mag fusion when field magnitude is large
Move mag inhibition check in separate function
* ekf_control: pull out of functionalities out of controlMagFusion
- yaw abd mag bias observability checks
- mag 3D conditions
- load mag covariances
- set and clear mag control modes
* ekf_control: refactor mag heading/3D start/stop.
Move mag declination, mag 3d and mag heading fusion out of the main function
* ekf_control: extract mag yaw reset and mag declination fusion requirements
* ekf_control: use WMM in isStronMagneticField for mag fusion inhibition
- Correct units of WMM strength table
* ekf_control: extract mag_state_only functionality of AUTOFW (VTOL custom)
Also split inAirYawReset from onGroundYawReset
* ekf_control: extract mag automatic selection
- transform if-else into switch-case for parameter fusion type selection
* ekf_control: extract run3DMagAndDeclFusion, reorganize functions, fix
flag naming in Test script
* ekf_control: do not run mag fusion if tilt is not aligned.
Reset some variables on ground even if mag fusion is not running yet. It
could be that it runs later so we need to make sure that those variables
are properly set.
* ekf_control: move controlMagFusion and related functions to mag_control.cpp
* ekf control: check for validity of mag strength from WMM and falls back
to average earth mag field with larger gate if not valid
* ekf control: remove evyaw check for mag inhibition
* ekf control: change nested ternary operator into if-else if
* Ekf: create AlphaFilter template class for simple low-pass filtering
0.1/0.9 type low-pass filters are commonly used to smooth data, this
class is meant to abstract the computation of this filter
* ekf control: reset heading using mag_lpf data to avoid resetting on an outlier
fixes ecl issue #525
* ekf control: replace mag_states_only flag with mag_field_disturbed and
add parameter to enable or disable mag field strength check
* ekf control: remove AUTOFW mag fusion type as not needed This was implemented for VTOL but did not solve the problem and should not be used anymore
* ekf control: use start/stop mag functions everywhere instead of setting the flag
* ekf control: Run mag fusion depending on yaw_align instead of tilt_align
as there is no reason to fuse mag when the ekf isn't aligned
* AlphaFilter: add test for float and Vector3f
Main UAVCAN protocol handling and ESC updates run on the same thread/wq as
before. There are 2 WorkItems for separate scheduling of the 2, so that
ESC updates run in sync with actuator_control updates. UAVCAN is scheduled
at a fixed rate of 3ms (previously the poll timeout) and on each UAVCAN
bus event.
This leads to roughly the same behavior as before. CPU & RAM usage are
pretty much the same (tested on Pixhawk 4).
Testing done: Motors still work (with feedback), param changes and a
UAVCAN optical flow sensor.
esc_setpoint in UAVCAN was just wrong, this is what it really is:
uint7 power_rating_pct # Instant demand factor in percent
(percent of maximum power); range 0% to 127%.
Currently actuator offboard control interferes with SITL lockstep.
Therefore, the least we can do is to warn a user and inform them how to
workaround the issue.
* PreFlightCheck: remove unused reportFailures flag
* Commander: pull all pre flight checks together on the PreFlightCheck class
* PreFlightCheck: separate checks into their own files
This fixes the case where the mixer_module would subscribe and use its
own test_motor publication which was created only to make sure the
topic is advertised and subsequent updates will work properly.
This happened in SITL lockstep because the timestamp would be 0 at the
very beginning, and hence elapsed time would be 0 as well.
This lead to an actuator publication which would then get lockstep out
of sync causing poll errors on the Gazebo side.
