CONTROL SYSTEMS
Objective :
In this course it is aimed to introduce to the students the principles and applications of control systems in
every day life. The basic concepts of block diagram reduction, time domain analysis solutions to time
invariant systems and also deals with the different aspects of stability analysis of systems in frequency
domain and time domain.
UNIT – I INTRODUCTION
Concepts of Control Systems- Open Loop and closed loop control systems and their differences- Different
examples of control systems- Classification of control systems, Feed-Back Characteristics, Effects of
feedback.
Mathematical models – Differential equations, Impulse Response and transfer functions – Translational
and Rotational mechanical systems
UNIT II TRANSFER FUNCTION REPRESENTATION
Transfer Function of DC Servo motor – AC Servo motor- Synchro transmitter and Receiver, Block diagram
representation of systems considering electrical systems as examples -Block diagram algebra –
Representation by Signal flow graph – Reduction using Mason’s gain formula.
UNIT-III TIME RESPONSE ANALYSIS
Standard test signals – Time response of first order systems – Characteristic Equation of Feedback control
systems, Transient response of second order systems – Time domain specifications – Steady state
response – Steady state errors and error constants – Effects of proportional derivative, proportional
integral systems.
UNIT – IV STABILITY ANALYSIS IN S-DOMAIN
The concept of stability – Routh’s stability criterion – qualitative stability and conditional stability –
limitations of Routh’s stability
Root Locus Technique:
The root locus concept – construction of root loci-effects of adding poles and zeros to G(s)H(s) on the root
loci.
UNIT – V FREQUENCY RESPONSE ANALYSIS
Introduction, Frequency domain specifications-Bode diagrams-Determination of Frequency domain
specifications and transfer function from the Bode Diagram-Phase margin and Gain margin-Stability
Analysis from Bode Plots.
UNIT – VI STABILITY ANALYSIS IN FREQUENCY DOMAIN
Polar Plots-Nyquist Plots-Stability Analysis.
UNIT – VII CLASSICAL CONTROL DESIGN TECHNIQUES
Compensation techniques – Lag, Lead, Lead-Lag Controllers design in frequency Domain, PID
Controllers.
UNIT – VIII State Space Analysis of Continuous Systems
Concepts of state, state variables and state model, derivation of state models from block diagrams,
Diagonalization- Solving the Time invariant state Equations- State Transition Matrix and it’s Properties –
Concepts of Controllability and Observability
