Function Documentation

stabilization_indi_attitude_run()

void stabilization_indi_attitude_run	(	struct Int32Quat	quat_sp,
		bool	in_flight
	)

runs stabilization indi

Parameters

enable_integrator
rate_control	boolean that determines if we are in rate control or attitude control

Function that should be called to run the INDI controller

Parameters

in_flight	not used
rate_control	rate control enabled, otherwise attitude control

Definition at line 496 of file stabilization_indi.c.

stabilization_indi_enter()

void stabilization_indi_enter

(

void

)

Function that resets important values upon engaging INDI.

Don't reset inputs and filters, because it is unlikely to switch stabilization in flight, and there are multiple modes that use (the same) stabilization. Resetting the controller is not so nice when you are flying. FIXME: Ideally we should detect when coming from something that is not INDI

Definition at line 256 of file stabilization_indi.c.

stabilization_indi_init()

void stabilization_indi_init

(

void

)

Function that initializes important values upon engaging INDI.

Definition at line 206 of file stabilization_indi.c.

stabilization_indi_rate_run()

void stabilization_indi_rate_run	(	struct FloatRates	rate_sp,
		bool	in_flight
	)

Does the INDI calculations.

Parameters

att_err	attitude error
rate_control	boolean that states if we are in rate control or attitude control
in_flight	boolean that states if the UAV is in flight or not

Function that calculates the INDI commands

Parameters

indi_commands[]	Array of commands that the function will write to
att_err	quaternion attitude error

Definition at line 347 of file stabilization_indi.c.

stabilization_indi_read_rc()

void stabilization_indi_read_rc	(	bool	in_flight,
		bool	in_carefree,
		bool	coordinated_turn
	)

This function reads rc commands.

Parameters

in_flight

boolean that states if the UAV is in flight or not

Definition at line 525 of file stabilization_indi.c.

stabilization_indi_set_earth_cmd_i()

void stabilization_indi_set_earth_cmd_i	(	struct Int32Vect2 *	cmd,
		int32_t	heading
	)

Set attitude setpoint from command in earth axes.

Parameters

cmd	2D command in North East axes
heading	Heading of the setpoint

Function that calculates the setpoint quaternion from a command in earth axes

Parameters

cmd	The command in earth axes (North East)
heading	The desired heading

Definition at line 323 of file stabilization_indi.c.

stabilization_indi_set_failsafe_setpoint()

void stabilization_indi_set_failsafe_setpoint

(

void

)

stabilization_indi_set_rpy_setpoint_i()

void stabilization_indi_set_rpy_setpoint_i

(

struct Int32Eulers *

rpy

)

Set attitude quaternion setpoint from rpy.

Parameters

rpy	rpy from which to calculate quaternion setpoint

Function that calculates the setpoint quaternion from rpy

Parameters

rpy	roll pitch yaw input
