Re: [Paparazzi-devel] Rotocraft horizontal speed limiting in flight plan?

[Felix Ruess]

Hi Luke,

I quickly implemented a dynamic max_speed in the gh_max_speed branch, see pull 664.

I haven't tested it, but you should be able to #include "guidance/guidance_h_ref.h" in your flight plan and call gh_set_max_speed(2.5) to set the current speed limit to 2.5m/s.

Cheers, Felix

Hi Luke,

for position/waypoint mode it can currently only be set at compile time, feel free to open an issue with a feature request for that so it can be tracked...

Shouldn't be much work to make it changeable via settings or from the flight plan...

Cheers, Felix

Felix,

 

Is there any way to change the maximum speed dynamically (i.e. with a SET command in a flight plan block), or can it only be changed at build-time?

Hi Mark,

 

you should be able to set the max speed by defining GUIDANCE_H_REF_MAX_SPEED in meters/second (defaults to 5 m/s) in your airframe file.

Hello,

I'm new to Paparazzi and have been banging my head a little too much in trying to figure out how to limit the speed of my quadrotor.  I've been working in the simulator with the Quad_Lisa_M2 AC, and also in the real world using an AR Drone as the platform.

I'm trying to get the AR Drone to do some automatic waypoint navigation through a flight plan.  It works, but it looks like the quadrotor is flying with maximum horizontal speed as it goes.  I'd like to be able to set a maximum horizontal speed in the flight plan.

I'd appreciate any suggestions on how to do this and/or pointers on what topics I should read up on.

Thanks a lot,
Mark
