This course has been designed to introduce the students with basic theory of Linear Control Systems. Given that all engineering processes are time varying in nature, it is highly desirable to be able to model and hence predict their behavior in time. This course initiates the skills necessary for the analysis, modification and achievement of specific behavior in physical and dynamic Engineering systems. After studying this course students should be able to derive mathematical models of physical systems and check stability of control system in Time and Frequency domain. The students should also be able to analyze transient as well as steady state behavior of linear time invariant systems and analyze steady state errors. Control system design will be demonstrated by using PID controllers. The subject will be supported by software simulations like MATLAB/LABVIEW to demonstrate real time simulations and control system implementation.
