COURSE
DESCRIPTION

The course deals with the analysis and design of modern control systems. Students will be made
familiarized with open
-
loop and closed
-
loop systems. Mathematical modeling of control
systems through transfer function and state space model will be studied exh
austively for
mechanical (translational and rotational) and electrical systems. Transient and steady state
analysis will be introduced. Root
-
locus analysis and design of the system by Root
-
locus method
will be studied. Students will be made capable of anal
yzing frequency response of Control
systems using Bode and Nyquist plot methods. At the last analysis of Control systems in State
Space Model will be introduced. The course directly contributes to
objectives

a, d, e and f of the
HEC Electrical Engineering
Curriculum.

EXPECTED
OUTCOMES

The course strongly supports expected
outcomes

a, b, d and i of the HEC Electrical Engineering
Curriculum.
Upon completion of this course, students will understand:

Root
-
locus Analysis



Frequency
-
Response Analysis using Bode and Nyquist Plot
