This course introduces the concepts of feedback and its advantages to various control systems
The performance metrics to design the control system in time-domain and frequency domain are introduced.
Control systems for various applications can be designed using time-domain and frequency domain analysis.
In addition to the conventional approach, the state space approach for the analysis of control systems is also introduced.
