First, can you please clarify how did you work out above equations? what are S_i and Z_i parameters? Moreover, as far as I can say from your answer, such major changes in two step responses with two significantly different sampling intervals are normal due to your rational. But nothing wrong with selecting T=0.0001 for my design. Right? | |
