Control systems from beginning for engineering students

In this chapter, we describe a general process for designing a control system. A control system consisting of interconnected components is designed to achieve a de-sired purpose. To understand the purpose of a control system, it is useful to examine examples of control systems through the course of history. These early systems incorporated many of the same ideas of feedback that are in use today.Modern control engineering practice includes the use of control design strategies for improving manufacturing processes, the efficiency of energy use, and advanced automobile control (including rapid transit, among others). We will examine these very interesting applications of control engineering and introduce the subject area of mechatronics. We also discuss the notion of a design gap. The gap exists between the complex physical system under investigation and the model used in the control system syn-thesis. The iterative nature of design allows us to handle the design gap effectively while accomplishing necessary trade-offs in complexity, performance, and cost in order to meet the design specifications.

In this course we are going to discuss Introduction to Control system, Block Diagram Representation, Transfer Function, System Stability, Routh Stability Criterion, Time Response and Steady State Error, Time Response Analysis, Root locus and etc.
