Script to update include paths:
for i in $(grep -rl 'include <px4_work_queue' src platforms); do sed -i 's/#include <px4_work_queue/#include <px4_platform_common\/px4_work_queue/' $i; done
This moves the hysteresis test out of the systemlib and makes it its own
small library. Since it still depends on hrt_absolute_time this does not
link yet. My attempt to get all link dependencies together failed.
instead of the derivative of the vertical position which is
not the same value when using the ekf2 estimation.
Using the position derivative resulted in delayed landing because
the value for some reason often bumped over the theshold before
slowly converging towards zero while the velocity was within expected
accuary in all these cases.
PositionControl: update comment about the order of thrust and position
mc_pos_control: reset setpoints to NAN if required
MulticopterLandDetector: consider to be landed if vehicle is not armed
mc_pos_control: initialize landing struct with landed
mc-pos-ctrl: adjust thrust-setpoint and yaw during ground-contact/maybe-landed without capturing
that information within vehicle-local-position-setpoint topic because that information
does not belong to user intention
PositionControl: set local position/velocity setpoint to NAN if not used in the control pipeline
mc-pos-ctrl: Fill vehicle_local_position_setpoint_s structure as follow:
The message contains setpoints where each type of setpoint is either the input to the PositionController
or was generated by the PositionController and therefore corresponds to the PositioControl internal states (states that were generated by P-PID).
Example:
If the desired setpoint is position-setpoint, _local_pos_sp will contain
position-, velocity- and thrust-setpoint where the velocity- and thrust-setpoint were generated by the PositionControlller.
If the desired setpoint has a velocity-setpoint only, then _local_pos_sp will contain valid velocity- and thrust-setpoint, but the position-setpoint
will remain NAN. Given that the PositionController cannot generate a position-setpoint, this type of setpoint is always equal to the input to the
PositionController.
mc_pos_control: switch to designated initializer for landed
It's less error prone because it produces an error on every discrepancy.
- no airframe changes the default
- it does not make much sense to be able to configure the 0.1 threshold
but the 0.3 threshold for ground contact detection cannot be configured.
