Function Documentation

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 254 of file stabilization_indi.c.

void stabilization_indi_init ( void  )

Function that initializes important values upon engaging INDI.

Definition at line 204 of file stabilization_indi.c.

void stabilization_indi_read_rc ( bool  in_flight,
bool  in_carefree,
bool  coordinated_turn 

This function reads rc commands.

in_flightboolean that states if the UAV is in flight or not

Definition at line 517 of file stabilization_indi.c.

void stabilization_indi_run ( bool  in_flight,
bool  rate_control 

runs stabilization indi

rate_controlboolean that determines if we are in rate control or attitude control

Function that should be called to run the INDI controller

in_flightnot used
rate_controlrate control enabled, otherwise attitude control

Definition at line 475 of file stabilization_indi.c.

void stabilization_indi_set_earth_cmd_i ( struct Int32Vect2 cmd,
int32_t  heading

cmd2D command in North East axes
headingHeading of the setpoint

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

cmdThe command in earth axes (North East)
headingThe desired heading
