FixedWingLongitudinalSetpoint (UORB message)

Fixed Wing Longitudinal Setpoint message. Used by the fw_lateral_longitudinal_control module. If pitch_direct and throttle_direct are not both finite, then the controller relies on altitude/height_rate and equivalent_airspeed to control vertical motion. If both altitude and height_rate are NAN, the controller maintains the current altitude.

TOPICS: fixed_winglongitudinal_setpoint

Fields

Назва	Тип	Unit [Frame]	Range/Enum	Опис
timestamp	uint64			time since system start (microseconds)
altitude	float32	m		Altitude setpoint AMSL, not controlled directly if NAN or if height_rate is finite
height_rate	float32	ENU		Scalar height rate setpoint. NAN if not controlled directly
equivalent_airspeed	float32	m/s	[0 : inf]	Scalar equivalent airspeed setpoint. NAN if system default should be used
pitch_direct	float32	FRD	[-pi : pi]	NAN if not controlled, overrides total energy controller
throttle_direct	float32	norm	[0 : 1]	NAN if not controlled, overrides total energy controller
