ST FOC Library v3.3: state observer + PLL coeff. calculation

Hi,

I�m using the state observer + PLL algorithm and am trying to understand how the coefficients are calculated by ST MC Workbench v2.1. I couldn�t find everything I wanted in the docs, so could anyone give me the equations for the following parameters:
  • F1 (scaling factor)
  • G1. This seems to be proportional to K1, but I couldn't find the equation anywhere in the docs. I only found the equation for K1 in the ST FOC library user manual and it yields the same result as ST Motor Control workbench.
  • F2 (scaling factor)
  • G2. Similar to G1, it seems to be proportional to K2;only the equation for K2 can be found in the user manual.

Many thanks for that.

I suggest to register your request in the online support:

with this reference: Motor control application.

We will try to contact you via a local ST office for the support.

The question has been moved from the "Motor Control Hardware" section to the "STM32 Motor Control" section (the question is about the STM32 MC SDK).
