Thanks a lot for your answer. This Zeppelin autopilot will be next winter project. I will keep the list informed of our progress. Cheers Cédric De : address@hidden [mailto:address@hidden De la part de Christophe De Wagter Standard fixedwing control loops will work for the zepplin, just do not use I-gains on attitude. -the outerloops requests a commanded roll angle depending on the trajectory. -the blimp obviously will not roll as it can't -the innerloop will deflect the actuator (rudder) until the desired roll angle is achieved: since the blimp will not roll it will deflect the rudder as long as the navigation commands to turn. to minimize the effect of real blimp roll (e.g. if the blimp turns out to roll-oscillate during a straight line) you can use a much higher max-bank, higher nav-gains and lower attitude-roll gains. if still not enough, edit the control loop code and set the measured phi to zero so the innerloop just passes outerloop commands to the actuator but that is probably not needed.
