afm11 - HE current control

added block previously created in afm8

started with a setpoint of 100 and Kp of 10

turned slowly

tried with Kp = 1

did not turn at all

tried Kp = 0.5

does not turn - efforts are very low

try Kp = 1 again and check the efforts

sometimes just manages to turn: efforts are about 100, add Ki = 1 as well

WORKS pretty well - check current on current clamp.


all current clamp measurements are on phase C

here is the image from the current clamp - 20A divisions drawing a bus voltage of about 5A



it looks like it is going oscillatory - try reducing Kp to 0.5



that may be a little better - try reducing to 0.2



definetly better - try 0.1



better again, however getting a bit weak - try Ki = 2



not really any better - try speeding up the controller loop with Kp = 0.1 and Ki = 1
