PID controller is a mechanism used in feedback control loops to automatically maintain a process parameter at a certain level. About 90% of all automatic control systems have this universal mechanism. In simple terms, the PID algorithm regulates a process variable by calculating a control signal ...
Table 1.1 Some Common Control Systems The systems shown in Table 1.1 are some of the simplest applications of control systems. More advanced control system applications appear in the fields of automotive, aerospace, chemical processing, and in many other areas. This book focuses on the design and...
Given their extremely rugged construction and reliable design, these control systems may continue to operate without significant trouble for decades. A somewhat newer, yet still legacy model of PLC manufactured by Allen-Bradley is the SLC 500 series, often verbally referred to as the “Slick 500”...
