Abstract
A perfect integrator emulator includes a first multiplier multiplying an input with a first constant, K , and generating a scaled input, a summer summing the scaled input with a previously generated scaled output and generating an accumulated output, a delay adding a predetermined amount of delay to the accumulated output and generating a delayed output, a second multiplier multiplying the delayed output with a second constant, K , and generating the scaled output. The constants K and K are chosen such that the accumulated output emulates a perfect integrator's relative weighting, and saturation protection is guaranteed.
