Lesson 1 Introduction to Industrial Automation and Control Version 2 EE IIT, Kharagpur 2
Background image of page 2
Lesson Objectives To define Automation and Control and explain the differences in the sense of the terms To explain the relation between Automation and Information Technology To underline the basic objectives of a manufacturing industry and explain how automation and control technologies relate to these To introduce the concept of a Product Life Cycle and explain how Automation and Control technologies relate to the various phases of the cycle To classify Manufacturing plants and categorise the different classes of Automation Systems that are appropriate for these Understanding the Title of the Course Let us first define the three key words in the title, namely, In this course, we shall be concerned with Manufacturing Industries only. Industry In a general sense the term “Industry” is defined as follows. Definition: Systematic Economic Activity that could be related to Manufacture /Service/ Trade. Automation The word ‘Automation’ is derived from greek words “Auto”(self) and “Matos” (moving). Automation therefore is the mechanism for systems that “move by itself”. However, apart from this original sense of the word, automated systems also achieve significantly superior performance than what is possible with manual systems, in terms of power, precision and speed of operation. Definition: Automation is a set of technologies that results in operation of machines and systems without significant human intervention and achieves performance superior to manual operation A Definition from Encyclopaedia Britannica The application of machines to tasks once performed by human beings or, increasingly, to tasks that would otherwise be impossible. Although the term mechanization is often used to refer to the simple replacement of human labour by machines, automation generally implies the integration of machines into a self- governing system.

Point to Ponder: 1 A. Why does an automated system achieve superior performance compared to a manual one? B. Can you give an example where this happens? Control It is perhaps correct to expect that the learner for this course has already been exposed to a course on Control Systems, which is typically introduced in the final or pre-final year of an undergraduate course in Engineering in India. The word control is therefore expected to be familiar and defined as under. Definition: Control is a set of technologies that achieves desired patterns of variations of operational parameters and sequences for machines and systems by providing the input signals necessary.
