This is done by inheriting from FlightTaskManualAltitudeSmoothVel again.
The altitude change by command is taken care of by switching
to the apporach when the altitude difference is big enough and
switching back once the altitude is close enough.
The altitude of the command is not perfectly reached but this can
only be done smoothly when the Orbit has full control over the
altitude smoothing. The independent altitude smoothing is not kept
because it was lacking stick handling like altitude lock and smooth
transitions when opening and closing the vertical position loop.
I think they were forgotten and it leads to side effects:
- The acceleration feed-forward does not get executed
- The acceleration setpoint is NAN when initializing the altitude
smoothing when arriving at the circle
Since the same parameter is used to generate the trajectory and to
saturate the controller, there is no additional space for the output of
the position controller once it is filled with the feedforward, letting
the altitude grow uncontrolled.
To avoid weird cases where the altitude is different enough and
the offtrack state flies to the target altitude instead of the closest
point on the track between the waypoints.
In MPC_YAW_MODE 3 (along trajectory), the flight task is asked to
produce a yaw setpoint. If the previous yaw value was NAN (e.g.: during
early takeoff), the setpoint should then be reset to the current
estimate.
It was meant as an example for an easy to use interface of a
motion primitive with a minimal implementation. But the implementation
is much worse than the jerk optimized trajectory. We rather
work on making it easier to use. #18390 was a first step towards that.
