In-depth PID research and tuning #21

Open MatzElectronics opened 7 years ago

MatzElectronics commented 7 years ago

Research/experiment with (and most importantly document the effects of) the full range of all individual PID settings. From there, optimize for the standard configuration, and make recommendations of common changes/configurations.

From @RoboTechie / #45 : While disabling the median filter on the SF11-C (Instructions here) fixes the catastrophic oscillations described in Issue 13, the ELEV-8 still oscillates 10-50 cm vertically without ever settling out when using the SF11-C for altitude hold, so any improvements to reduce this would be well received.

Is this with a big battery or a gimbal, or the 3300 battery and no additional hardware? (I agree it needs tuning, but I seemed to have fewer issues than reported).

Ideally a comprehensive and deep dive into this - multiple configurations, so we know how various settings, loads, and configurations impact different aspects of the craft's performance, both in terms of setpoints and range.

I meant specifically what config are you flying where you're seeing the oscillation?

I was using a 5300mah battery (which I consider the "standard" for the v3) other than that, the only other payload was the laser sensor and a ping sensor.

Ok, good to know. I typically fly with the 3300mah.
