INTRODUCTION[/b]


Process control is a statistics and engineering discipline that deals with architectures, mechanisms, and algorithms for controlling the output of a specific process. Industrial processes involve chemical or mechanical steps to aid in the manufacture of an item or items, usually carried out on a very large scale. Industrial processes are the key components of heavy industries in aacquiring an accurate and timely measurements is the foundation of any industrial monitoring or control system.

At the onset of the Industrial Revolution, processes were controlled manually. Men turned valves, pulled levers or changed switches based on the need to turn devices on or off. Automation (ancient Greek: = self dictated), or industrial automation or numerical control is to control industrial machinery and processes, reducing the need for human intervention. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provides human operators with machinery to assist them with the physical requirements of work, automation greatly reduces the need for human sensory and mental requirements as well. As the technology of process control evolved, the human links in the process were replaced by products that could automatically make the mechanical adjustments that were necessary, and make them accurately and consistently. This resulted in increased efficiency and greater productivity from the machine, process and operator. Today, the process industry experiences greater demands for productivity and efficiency. The requests for more exotic materials have enhanced the development of products that provide more exacting control.

Most processes makes the production of materials vastly cheaper, thus changing it into a commodity; i.e. the process makes it economically feasible for society to use the material on a large scales, in machinery, or a substantial amount of raw materials, in comparison to batch or craft processes. Production of a specific material may involve more than one type of process. Most industrial processes result in both a desired product(s) and by-products, many of which are toxic, hazardous, or hard to deal with. Very, very few processes are self-contained. The main aim is to process and control such hazardous situations. When it comes to designing new machines or optimizing the existing plants, remaining competitive in the industrial market is a challenging task.
