Design and Analysis of an Electronic Peak-Holding Controller

Peak-holding control offers a simple and inexpensive method whereby operation of a certain class of processes may be kept in the region of optimum performance. The design of an electronic peak-holding controller is described in this paper, and techniques for analyzing its behavior are presented. The possible occurrence of spurious (false) peaks being detected by the controller is demonstrated and a method of both predicting and preventing this peak detection phenomenon is developed. Application of the controller in optimizing the feed rate to a simulated pebble mill grinder is presented.
