Hi,
I am using a 500CPR optical encoder to do vector control I measure the rotor speed by a fixed time interval. I compare the measure speed with the signal from the encoder output channel and found it slightly higher than the one I measured.but the encoder output channel has a little bit jitter which makes me difficult to estimate the true speed. How can I konw the real speed of motor? Anyone successfully used an optical encoder in vector control?It would be very helpful if you can share your source code or experience Thanks! |
