Formular of Feed Forward Control Constants

SF??r
Associate III

Hi,

 

the MotorControlWorkbench is generating the Feedforward control constants:

M1_CONSTANT1_Q

M1_CONSTANT1_D

M1_CONSTANT2_QD

How are the calculated, are there any documentation or formula for it?

The Feedforward seems to be relevant for my project because I see current ripple aligned with my DC bus voltage ripple. But in practice there is no improvement, if I activate the FeedForward control. Also the bus voltage is measured with 1 ms and a filter with 6 values is applied. Are there any tips for my application if I have a bus voltage ripple period of 10 ms (3 Phase, 50 Hz)?

 

Thanks for Help

 

Sebastian
