AIM
To provide sound knowledge in the basic concepts of linear control theory and design of control system.
OBJECTIVES
i. To understand the methods of representation of systems and getting their transfer function models.
ii. To provide adequate knowledge in the time response of systems and steady state error analysis.
iii. To give basic knowledge is obtaining the open loop and closed–loop frequency responses of systems.
iv. To understand the concept of stability of control system and
methods of stability analysis.
v. To study the three ways of designing compensation for a control system.
