( That's about 30 years of dust mind!!!!) Time to dust off my understanding of Z transforms. I wonder if they have used digital filters. As for PID control, that would be interesting to see. Jhankey wrote:Enesto, looks like Johandewit is another engineer. So would it not be possible to supply us (or me) with 2 JSON files a file with adjusted settings that give the trainer more responsiveness, and two a file that reflects the default settings as they are currently used (so that we can revert back to the current situation). I can not imagine that the Drivo core is much different from our Direto XR core, so I expect that in our trainers it should also be possible to adjust the parameters of the PID controller. The picture 4169 shows the behavior one would expect and they also report back that with these settings the trainer is quick enough to respond to 10 second power jump intervals. I notice that users pryswilliams and 4169 report back good results using the updated parameters. Based on the names I assume it's setting the PID controller parameters for the PID controller that Elite implemented in the trainers to maintain the power required. When you look at the file you will see that is sets some parameters on some addresses in the trainer. I noticed that early this year Elite supplied some of the Drivo users a JSON file that they can upload to their trainer using the Upgrado app. I took some time to read in the Drivo/Drivo II thread where they reported similar issues with EGR mode. PS this is the thread with more replies of the whole DIRETO section in the forum.
Goldencheetah szwift workout software#
or use the elite software where you can find the native csv export for the activity.
I renew the invite to Elite to share more tech details and to explain the source of such differences in performances and to share if there is a way to perform some HW check/analysis on our to get excel you can export the workout from zwift ( in *.fit I think) import the workout in golden cheetah and then export the csv. Or we are a group of crazy people with a hard dependence of scattering charts, standard deviations and smoothing average values, or something is not working on our devices. Now it is shiny clear that the results we saw on youtube/reviews (and that influenced us to buy this trainer and not another one) are far away from what we are getting here, so I don't think we have hundreds of hypotesis on the table. Starting to feel that I am doing Elite's work for them!!!īTW I agree with your analysis, it makes perfectly sense, but I think Elite could reply with some tech info (n° of meas per stroke, best cadence/gear ratio, etc, power ceiling/floor), just to avoid all this "debunking" effort where we all here are falling (and let me add, it seems to me that we all are doing our best to get the same best from our devices!) I could then take the data sets and run an FFT on them to look at what fundamentals are in the data sets
