Thrust tilt/ Starboard Thrust / Port Thrust / Tail Thrust mixer for PX4FMU
|
||
|
|
=======================================================
|
||
|
|
|
||
|
|
This file defines mixers suitable for controlling an airship with
|
||
|
|
a thrust tilt, starboard and port thruster and a tail thruster using PX4FMU.
|
||
|
|
The configuration assumes the starboard thruster is connected to PX4FMU
|
||
|
|
output 1, port thruster to output 2, tilt servo to output 3, and the
|
||
|
|
tail thruster to output 4.
|
||
|
|
|
||
|
|
Inputs to the mixer come from channel group 0 (vehicle attitude),
|
||
|
|
channels 0 (roll), 1 (pitch), 2 (yaw) and 3 (thrust).
|
||
|
|
|
||

Starboard and port thruster mixer
|
||
|
|
-----------------
|
||
|
|
Two scalers total (output, thrust).
|
||
|
|
|
||
|
|
By default mixer output is normalized. The input is in the (0 - 1) range.

Servo controlling tilt mixer
|
||
|
|
------------
|
||
|
|
Two scalers total (output, tilt angle).
|
||
|
|
|
||
|
|
This mixer assumes that the tilt servo is set up correctly mechanically;
|
||
|
|
depending on the actual configuration it may be necessary to reverse the scaling
|
||
|
|
factors (to reverse the servo movement) and adjust the offset, scaling and
|
||
|
|
endpoints to suit.

Tail thruster mixer
|
||
|
|
------------
|
||
|
|
Two scalers total (output, yaw).
|
||
|
|
|
||
|
|
This mixer assumes that the tail thruster is set up correctly mechanically;
|
||
|
|
depending on the actual configuration it may be necessary to reverse the scaling
|
||
|
|
factors (to reverse the motor movement) and adjust the offset, scaling and
|
||
|
|
endpoints to suit.
