hi, I simulated a DC motor with the help of Simscape and determined the RPM with the help of an encoder. The encoder generates 4 pulses per rev. For decoding I counted the falling edges of Port A with Counter UP and the counter is reset to zero every second (time interval) using Pulse Generation. The number of pulses per second is divided by 4 (4 pulses per rev) and multiplied by * 60 (from sec to minute). How could I simulate the rotional speed (RPM) continuously ? so that the RPM always stays at the same value, as long as the voltage is not changed. Because every second it is reset to zero (see RPM image) if I do not set the counter to zero every second then it will continue to count.
