# Modules Reference: Controller
# ODULE_NAM
Source: modules/control_allocator (opens new window)
# Description
This implements control allocation. It takes torque and thrust setpoints as inputs and outputs actuator setpoint messages.
# Usage
ODULE_NAM <command> [arguments...]
Commands:
start
stop
status print status info
# airship_att_control
Source: modules/airship_att_control (opens new window)
# Description
This implements the airship attitude and rate controller. 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.
# Implementation
To reduce control latency, the module directly polls on the gyro topic published by the IMU driver.
# Usage
airship_att_control <command> [arguments...]
Commands:
start
stop
status print status info
# flight_mode_manager
Source: modules/flight_mode_manager (opens new window)
# Description
This implements the setpoint generation for all modes. It takes the current mode state of the vehicle as input and outputs setpoints for controllers.
# Usage
flight_mode_manager <command> [arguments...]
Commands:
start
stop
status print status info
# fw_att_control
Source: modules/fw_att_control (opens new window)
# Description
fw_att_control is the fixed wing attitude controller.
# Usage
fw_att_control <command> [arguments...]
Commands:
start
[vtol] VTOL mode
stop
status print status info
# fw_pos_control_l1
Source: modules/fw_pos_control_l1 (opens new window)
# Description
fw_pos_control_l1 is the fixed wing position controller.
# Usage
fw_pos_control_l1 <command> [arguments...]
Commands:
start
[vtol] VTOL mode
stop
status print status info
# mc_att_control
Source: modules/mc_att_control (opens new window)
# Description
This implements the multicopter attitude controller. It takes attitude
setpoints (vehicle_attitude_setpoint
) as inputs and outputs a rate setpoint.
The controller has a P loop for angular error

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

# mc_pos_control
Source: modules/mc_pos_control (opens new window)
# Description
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 (opens new window)
# Description
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

# navigator
Source: modules/navigator (opens new window)
# Description
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.
# Implementation
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 4 fake transponder_report_s uORB messages

# rover_pos_control
Source: modules/rover_pos_control (opens new window)
# Description
Controls the position of a ground rover using an L1 controller.
Publishes actuator_controls_0
messages at IMU_GYRO_RATEMAX.
# Implementation
Currently, this implementation supports only a few modes:
- Full manual: Throttle and yaw controls are passed directly through to the actuators
- Auto mission: The rover runs missions
- Loiter: The rover will navigate to within the loiter radius, then stop the motors
# Examples
CLI usage example:
rover_pos_control start
rover_pos_control status
rover_pos_control stop
# Usage
rover_pos_control <command> [arguments...]
Commands:
start
stop
status print status info
# uuv_att_control
Source: modules/uuv_att_control (opens new window)
# Description
Controls the attitude of an unmanned underwater vehicle (UUV).
Publishes actuator_controls_0
messages at a constant 250Hz.
# Implementation
Currently, this implementation supports only a few modes:
- Full manual: Roll, pitch, yaw, and throttle controls are passed directly through to the actuators

uuv_att_control status
uuv_att_control stop
