## Course Objectives

This course presents an introduction to feedback control systems. Control systems have importance in all fields of engineering. The objective is to provide the student with the basic concepts of control theory as developed over the years in both frequency and time domain.

## Course Learning Outcomes (CLO)

CLO-1: Make mathematical models of different physical system.  The gained knowledge to be applied to physical systems to determine the stability, fastness, slowness or oscillations. (C3)

CLO-2: Analyze complex engineering problems using mathematical models to examine different properties of the system. (C4)

CLO-3: Develop a controller to achieve the desired response from the system by using the knowledge developed in the analysis process. (C5)
