Part Number: DRV8301-69M-KIT
hey guys,
how do I set different Kp and Ki for different speeds? I'm not sure how to do that, is there any lab for this or do I
have to implement it. If so, I would like to link the speed-feedback with the Kp and Ki values is this ok?
Should I multiply the Kp and Ki values with the speed-feedback or set a fix edge with values, like this
if(speed-feedback<100)
kp and ki=...
else if(speed-feedback<1000)
kp and ki=...
I'm building an electric car. At the moment I use the drv8301-69m kit with 1mOhm shunts for more current (adc-full-scale 165, iq-scale-current 82.5).
I use lab 5a. When I increase the iq_ref not too rapidly it works great. When I drive with about 10A and then I increase the iq_ref too
rapidly the motor begins to jitter. I tried different Kp and Ki now it works slightly better.
I want to try different Kp and Ki for different speeds.
But would I have better results with instaspin motion?
Could be the motor too small for my desired acceleration?
(it weighs about 30 kg, it is a 1800W motor and the translation is rather for acceleration)
thanks in advance
