Moving Average Filter in Simulink

I'm rotating an electric machine by using dSPACE This machine has two phases and that's why I need to know the average current and voltage for a period of 180 degree.

I searched for a moving average filter in Simulink but I'm not able to find what I want. The sample time is fixed and the speed of the electric machine will vary. This means that by using different rotational speeds the number of samples should be different to cover the period of 180 degree.

What will be the easiest way to do this? (using memory blocks is not an option because than I need several hundreds of them). Is there maybe a nice function block what is able to do this?

Hi Thanks for your reaction. I guess I found a solution. It's a mean block in simscape with a variable frequency.

You can use a Matlab function block, and declare the current and voltage variables as persistent.
