AIM
To familiarize the students with concepts related to the operation analysis and
stabilization of control systems
OBJECTIVES
 To understand the open loop and closed loop (feedback ) systems
 To understand time domain and frequency domain analysis of control systems
required for stability analysis.
 To understand the compensation technique that can be used to stabilize control
systems
