MATLAB: How to get the average frequency for the hysteresis band control

Question

I am simulating a Direct torque control induction motor. Want to know the average frequency. How do i get it from the switching signals, or voltage signals? basically, i need a pulse counter, how to realize that? Thanks,

Answer 1

As you want a pulse counter, you can model it using a triggered subsystem. The subsystem can be configured to enable on the rising edge. Implement a counter inside the subsystem using a constant block(value=1), add block and a delay block. So, each time the subsystem encounters a rising edge, it adds 1 to the previous value and starts counting.

You can refer to the following links to know more about triggered subsystems
