Feedback control has been used for centuries to regulate engineered systems. In the 17th century, Cornelius Drebbel invented one of the earliest devices to use feed-back, an incubator that used a damper controlled by a thermometer to maintain a constant temperature. 1. Feedback devices became more prevalent during the indus-
