Other Parts Discussed in Thread: DRV8305
Hello
I am using motor which could run upto 80000rpm. I am using Piccolo28027f and DRV8305 for controlling motor.
Motor specifications are:
Inertia 3.15 kg-m2, Continuous stall current=3.31A, Peak torque=122.9Mnm, Continuous stall torque=7.98mNm, Inductance=0.030mH,Resistance=0.46 ohm
I started with lab 1 and finished upto lab05b. By using Lab02 i found out valyues of Rs, Ls_d and Ls_q, Flux.
Rs=0.46ohm
Ls_d & Ls_q=0.000030H
Flux=0.0042794
Also I am getting,
spd_kp=10.8
spd-ki=0.0542
idq-kp=0.150
idq-ki=0.767
But for these values motor doesn't run smoothly. It takes more current. But if I change
spd_kp=10.8
spd-ki=0.0542
idq-kp=0.00150
idq-ki=0.0767 Motor runs perfectly fine and current it takes is also very less.
why it is happening & how to change these parameters.
