Detailed Description

Guidance controllers (horizontal and vertical) for Hybrid UAV configurations.

Definition in file guidance_hybrid.h.

Function Documentation

void guidance_hybrid_airspeed_to_attitude ( struct Int32Eulers ypr_sp)

Convert a required airspeed to a certain attitude for the Hybrid.

Parameters
ypr_spAttitude set-point

Convert a required airspeed to a certain attitude for the Hybrid.

if required speed is lower than 4 m/s act like a rotorcraft

if required speed is higher than 4 m/s act like a fixedwing
