Re: [Paparazzi-devel] Control loops

[Loic Drumettaz]

Pitch_of_vz is the feedforward term of the throttle-pitch vertical control loop.That  loop has for input=desired climb (climb or vertical speed vz), and for output= throttle and pitch.
The pitch_of_vz is how much pitch (theta) you want for a given vertical speed (vz).
Loiter is a setting that reduces airspeed.
"z_dot" vertical speed, "z" vertical position. "estimator" for kalman filter output.

Hi all,
       recently，I learn something about paparazzi uav control loops at
http://wiki.paparazziuav.org/wiki/Control_Loops; some problems I encountered
as follow:
       1.“v_ctl_pitch_of_vz”,what does it mean?
       2."loiter()",what does it mean?
       3.what is the difference between "estimator_z_dot" and "estimator_z"?
Mike
