airship_att_control

Source: modules/airship_att_control

설명

이것은 비행선 자세 및 속도 컨트롤러를 구현합니다. Ideally it would take attitude setpoints (vehicle_attitude_setpoint) or rate setpoints (in acro mode via manual_control_setpoint topic) as inputs and outputs actuator control messages.

Currently it is feeding the manual_control_setpoint topic directly to the actuators.

     [vtol]      VTOL mode

   stop

   status        print status info

mc_pos_control

Source: modules/mc_pos_control

설명

The controller has two loops: a P loop for position error and a PID loop for velocity error. Output of the velocity controller is thrust vector that is split to thrust direction (i.e. rotation matrix for multicopter orientation) and thrust scalar (i.e. multicopter thrust itself).

The controller doesn't use Euler angles for its work, they are generated only for more human-friendly control and logging.

Usage

mc_pos_control <command> [arguments...]
 Commands:
   start
     [vtol]      VTOL mode

   stop

   status        print status info

mc_rate_control

Source: modules/mc_rate_control

설명

This implements the multicopter rate controller. It takes rate setpoints (in acro mode via manual_control_setpoint topic) as inputs and outputs actuator control messages.

The controller has a PID loop for angular rate error.

Usage

mc_rate_control <command> [arguments...]
 Commands:
   start
     [vtol]      VTOL mode

   stop

   status        print status info

navigator

Source: modules/navigator

설명

Module that is responsible for autonomous flight modes. This includes missions (read from dataman), takeoff and RTL. It is also responsible for geofence violation checking.

구현

The different internal modes are implemented as separate classes that inherit from a common base class NavigatorMode. The member _navigation_mode contains the current active mode.

Navigator publishes position setpoint triplets (position_setpoint_triplet_s), which are then used by the position controller.

Usage

navigator <command> [arguments...]
 Commands:
   start

   fencefile     load a geofence file from SD card, stored at etc/geofence.txt

   fake_traffic  publishes 24 fake transponder_report_s uORB messages
