Hi everyone,
I am using the Surface Mount PMSM block from the Motor Control Blockset in Simulink to develop an FOC algorithm. The output of the block (PhaseCurr) is a 1-by-3 array containing my 3 phase currents a, b and c. How can I extract the 2 currents (phase a and b) from my array in Simulink so that I can process them in the Clarke transform ? Please any help would be appreciated.

Use a Demux block with three outputs to extract the three signals, and then another Mux block with two inputs to combine the two you want again.

Hi, thanks again for you answer @Jonas. By any chance have you used Simulink's Motor Control Blockset before (MATLAB 2020a) ? I am struggling to understand how to set up a few blocks in there to develop a Field-Oriented Control algorithm. Your help would be really appreciated.
