Hello.
I'm trying to write my own soft for Field Oriented Control of induction motor. I have finished 3ph 3kW inverter, controled by STM32F4, and V/F open loop algorithm to control ACIM - it works. Now I'm trying to implement FOC algorithm.
As we know we need to do Clark&Park transformation.
To calculate Park transformation it's necessary to know rotor angle flux position. Here some details:

Another note propose to use speed integration to do this:

Could anyone expalin how to do this exactly?
I'm measuring currents (5kHz sampling), calculate Clark and measure speed, slip also.
Thanks for any response.
