Abstract
This paper compares the performances achieved with the conventional digital redesign techniques with those obtained with the modern global digital redesign methods such as the plant input mapping methods and the optimal digital redesign approach. The study based on a benchmark control system reveals that the reduced-order plant input mapping method, and not the optimal approach, offers what practicing control engineers are really looking for: simple controllers having a superior behavior in face of finite word length effects and over a relatively large band of sampling frequencies.
