MG University S6 Electrical and Electronics (EEE) B.Tech Syllabus
Module 1
Introduction: Concept of a system – control system – open-loop system – levels of
sophistication in a control system – mathematical model of physical systems –
plant representation – transfer functions – block diagrams – signal flow graphs –
effects of feedback on parameter variations, system dynamics and disturbance
signals.
Module 2
Time response analysis: Type and order of a system – time domain analysis of
systems – typical test input signals – response of first order systems to unit step,
unit ramp, and unit impulse signals – step response of second order systems –
performance characteristics of feed back control systems – time domain
behaviour from pole-zero plot
Steady state errors and error constants – generalized error constants –
improvement of performance by derivative control, integral control, PID control.
Module 3
Concepts of Stability: BIBO stability – asymptotic stability – Routh Hurwitz stability
criterion – relative stability – root locus technique – construction of root loci – root
contours – systems with transportation lag.
Module 4
Frequency response analysis: Correlation between time and frequency response –
polar plots – bode plots – relative stability – phase margin and gain margin –
minimum and non-minimum phase systems.
Module 5
