Auto tuner for PID gains

Posted by M Chehadeh on March 14, 2017 at 1:52pm

Greetings All,

I would like to hear a feedback from you about a possible product.

I am working on an auto-tuner that can tune PID parameters in flight. The tuning is safe and fast.

How helpful is this going to be for hobbyists?
Are there existing auto-tuners used in flight controllers? How good they are?

Thanks,

    I am aware of PID autotuners for process control, they are definitely there. Check RFT auto-tuners for example.

    What sort of input params or measurement equipment might be needed to feed your program?

    There is no special equipment used. But a special controller put instead of the PID controller is used. That special controller will do the identification and will calculate PID values.

    And yeah, the method am working on can give you "optimal" (heah that is debatable) PID values. So you can "tighten" your existing PID tuning.
