Please provide the algorithm for calculating the regulator parameters

I need a way to manually calculate the parameters for the speed, torque and flux regulators.
The reason is that the MCWB tool is too inaccurate and cannot handle the parameters of our motor.

The tool messes with following motor values:
- Rs of 5.825mΩ gets converted to 0.01Ω
- Ls of 3.715µH gets converted to 0.004mH

 

Alternatively, can you provide me with correct regulator parameters for these motor values?

I found the formulae in the MCSDK User Manual under "A priori determination of flux and torque current PI gains".

Regarding that, I already have two questions:
- How is Aop represented? This is supposed to be the "current sense amplification network". Is it a resistance? Voltage?
- What's the meaning of the "3.3" in the A transfer function block? Is this supposed to be the ADC reference voltage?
If that's the case, what happens in systems that don't use 3.3V as reference voltage? Will the calculations done by the MCWB be wrong as well? In our system we're using 3.03V.
- where to set/get the ωc value from?

Hey @DMeie.2 

Could you please share this user manual? I am looking for the same information

Huge Thanks!
