Abstract
Traditionally, servo engineers hale designed discrete-time lead compensator s by first designing a lead compensator in the w-domain, and then converted to the z-domain by using a bilinear transformation with frequency prewarpi ng. This technical note presents two new. simple formulas for determining t he zero and the pole of a discrete-time lend compensator directly in the z- domain from the desired maximum phase lend and the desired frequency at whi ch that phase lead should occur.
