1.0 - Introduction

Process control, is a mixture between the statistics and engineering discipline that deals with the mechanism, architectures, and algorithms for controlling a process. Process control has become increasingly important in the process industries as a consequence of global competition, rapidly changing economic conditions, faster product development, and more stringent environmental and safety regulations. (Peter J. Woolf, 2006)

Peter J. Woolf (2006) states further, the role of process control has changed throughout the years and is continuously shaped by technology. The traditional role of process control in industrial operations was to contribute to safety, minimized environmental impact, and optimise processes by maintaining process variables near the desired values.

In the past, processes which required continuous monitoring were maintained by process engineers manually. However, as stated by Peter J. Woolf in regards to process control being continuously shaped...
