Hello,
I am using a optical encoder to measure the speed of an induction motor(max 3000 rpm) for vector control,my DSP has QEP interface and I just read the timer-counter periodically for speed measurement. But I found out this speed measurement algarithm is not quite accurate,is there any better speed measurement algarithm? I would be very grateful if anyone can provide any extra links or reference about this area! Thanks!
