Course Outcomes 
This course introduces the concepts of feedback and its advantages to various control systems

The performance metrics to design the control system in timedomain and frequency domain are introduced.

Control systems for various applications can be designed using timedomain and frequency domain analysis.

In addition to the conventional approach, the state space approach for the analysis of control systems is also introduced.
