EE2253 CONTROL SYSTEMS Syllabus
UNIT I SYSTEMS AND THEIR REPRESENTATION
Basic elements in control systems – Open and closed loop systems – Electrical analogy of
mechanical and thermal systems – Transfer function – Synchros – AC and DC servomotors – Block
diagram reduction techniques – Signal flow graphs.
UNIT II TIME RESPONSE
Time response – Time domain specifications – Types of test input – I and II order system response –
Error coefficients – Generalized error series – Steady state error – P, PI, PID modes of feed back
control.
UNIT III FREQUENCY RESPONSE
Frequency response – Bode plot – Polar plot – Determination of closed loop response from open
loop response – Correlation between frequency domain and time domain specifications.
UNIT IV STABILITY OF CONTROL SYSTEM
Characteristics equation – Location of roots in S plane for stability – Routh Hurwitz criterion – Root
locus construction – Effect of pole, zero addition – Gain margin and phase margin – Nyquist stability
criterion.
UNIT V COMPENSATOR DESIGN
Performance criteria – Lag, lead and lag-lead networks – Compensator design using bode plots.
