Eee 3-1 Control Systems Important Topics
UNIT – I
Mathematical Modelling of Control Systems
Classification of control systems - open loop and closed loop control systems and their differences -
Feedback characteristics - transfer function of linear system, differential equations of electrical networks-
translational and rotational mechanical systems - transfer function of Armature voltage controlled DC
servo motor - block diagram algebra - signal flow graph – reduction using Mason’s gain formula.
UNIT-II
Time Response Analysis and Controllers
Standard test signals – time response of first and second order systems – time domain specifications -
steady state errors and error constants - effects of proportional (P) - proportional integral (PI) -
proportional derivative (PD) - proportional integral derivative (PID) systems.
Stability Assessment Techniques
The concept of stability – Routh’s stability criterion – limitations of Routh’s stability, root locus concept
– construction of root loci (simple problems) - Effect of addition of Poles and Zeros to the transfer
function.
UNIT–III
Frequency Response Analysis
Introduction to frequency domain specifications – Bode diagrams – transfer function from the Bode
diagram –Polar plots, Nyquist stability criterion- stability analysis using Bode plots (phase margin and
gain margin).
