Matthias Grob 4fc3f07cb1 ActuatorEffectiveness: add function to delectively stop motors with zero thrust 2023-07-10 19:00:52 +02:00
Silvan Fuhrer 1e56d9c219 Rework flaps/spoilers logic
- remove deprecated actuator_controls[INDEX_FLAPS/SPOILERS/AIRBRAKES]
- use new topic normalized_unsigned_setpoint.msg (with instances flaps_setpoint
and spoilers_setpoint) to pass into control allocation
- remove flaps/spoiler related fields from attitude_setpoint topic
- CA: add possibility to map flaps/spoilers to any control surface
- move flaps/spoiler pitch trimming to CA (previously called DTRIM_FLAPS/SPOILER)
- move manual flaps/spoiler handling from rate to attitude controller

FW Position controller: change how negative switch readings are intepreted
for flaps/spoilers (considered negative as 0).

VTOL: Rework spoiler publishing in hover

- pushlish spoiler_setpoint.msg in the VTOL module if in hover
- also set spoilers to land configuration if in Descend mode

Allocation: add slew rate limit of 0.5 to flaps/spoilers configuration change

Instead of doing the flaps/spoilers slew rate limiting in the FW Position Controller
(which then only is applied in Auto flight), do it consistently over all flight
modes, so also for manual modes.

Beat Küng 4087c27e84 control_allocator: handle saturation flags for helicopters 2022-09-07 08:00:27 +02:00
Beat Küng 76d8d8cae6 control_allocator: generic motor configuration for standard vtols
This adds the pusher/puller to the standard motors and makes the axis
configurable.

Silvan Fuhrer df0e402c44 CA: refactor logic for matrix updating
-pass flag EffectivenessUpdateReason into effectiveness, indicating if there was an external
update or not. Reasons for external updates are:
  -config changes (parameter)
  -motor failure detected or certain redundant motors are switched off to save energy

Beat Küng 5259877b1b control_allocator: update matrix normalization
- only normalize rpy for MC matrices
- for thrust use the 3D vector, so it works for FW and tilt rotors as well

This keeps MC unchanged.

Beat Küng 70e46a194f control_allocator: major refactoring & additions
- allow effectiveness matrix to select control allocator method
  (desaturation algorithm)
- add actuator_servos publication
- add support for multiple matrices (for vtol)
- add updateSetpoint callback method to actuator effectiveness to allow it
  to manipulate the actuator setpoint after allocation
- handle motor stopping & reversal
- add control surfaces & tilt servos
- handle standard vtol + tiltrotor
- rename MC rotors params & class to be more generically usable
- fixes and enables ActuatorEffectivenessRotorsTest

bresch f09b34007e CA: reload CA matrix to newly created CA class properly
Also remove the dependency of ActuatorEffectivenessMultirotor
to param update uORB topic; the CA module
sends a "force" parameter when needed

Beat Küng 0e66b0876b control_allocator: change SequentialDesaturation to existing MC mixer
And limit the operations to the number of configured outputs.

Only using the number of configured actuators reduces CPU load by ~2% on
F7 @1khz.

Beat Küng 308f614735 refactor control_allocator: directly get the effectiveness matrix when updated
Reduces stack + RAM usage
2021-01-18 11:25:37 -05:00
343cf5603e initial control allocation support
- control allocation module with multirotor, VTOL standard, and tiltrotor support
 - angular_velocity_controller
 - See https://github.com/PX4/PX4-Autopilot/pull/13351 for details
