I cant find THROTTLE_P ?????

Posted by DaveyWaveyBunsenBurner on December 21, 2010 at 3:59am

Hi,

 

I need to slow my plane down in AUTO, apparently this is the PID value THROTTLE_P, but I can't find this anywhere.

 

Has it been renamed?

 

I can find THROTTLE_ALT_P and THROTTLE_TE_P but I'm not sure.

 

Any guidance appreciated. Incidently, throttle in RTL seems a lot gentler and I thought the one value covers both?

 

Cheers

 

Dave

    The parameters currently in use are THROTTLE_TE_P or THROTTLE_ALT_P.  Use the first if you have an airspeed sensor and the second if you do not.

    Martin,

    Appreciate your help but Im on AP and not APM (should have mentioned that in the first place!)

    I have those settings configured in my AP config but think they affect fly by wire modes only.

    Looking in the flight tuning guide here: http://code.google.com/p/ardupilot/wiki/FlightTips

    They reference the PIDs for altitude hold but I cant see the same ones.

    I have a feeling theyve been renamed but not sure which is the correct one.

    Thanks again,

    Dave

    Hi Dave, I think all the information you need is here there is a section on the throttle use about 3/4 the way down the page.

     

    In the Config.h file I have added this code, I have it set to the following:

     

    #define THROTTLE_MIN         0 
    #define THROTTLE_CRUISE   50 
    #define THROTTLE_MAX        80 

    This seems to keep all in order on my ez*, have you tried this ?

     

    Regards
