EC25C12:
Control
Systems
Course
objective:
Model
physical systems using differential equations, transfer functions, and
state-space, then analyze time/frequency behavior to design stable,
high-performance controllers.
Introduction
To Control System
Fundamental
concepts of Control Systems: open loop and closed loop systems – Control system
Terminology – Applications.
Modelling
of Physical Systems:
Transfer
function – Modelling of Electric systems, Translational and rotational
mechanical systems, Electrical analogous systems. Block diagram reduction,
signal flow graphs, multivariable control system.
Time
Domain Response
Transient
and Steady state response - Standard test inputs - Time response of first and
second order systems - Time domain specifications. Effect of moving the pole in
the s-plane, Effect of adding real pole and zero. Steady state error, error
constants and system type.
Stability
Analysis
Concept
of stability, characteristic equation, location of poles. Routh Hurwitz
stability criterion - Root locus technique.
Frequency
Domain Response
Frequency
response: Frequency response of standard second order system - Frequency domain
specifications - Relationship between Frequency and time domain specifications
– Plots: Bode and Polar - Nyquist stability criterion.
Controller
and Compensator Design
Controllers:
P, PI, PD, PID - Analytical design of controllers. Compensators: needs and its
types - Design of lag, lead, lag-lead compensators using root locus and bode
plot.
State
Space Representation
Concept
of state, state variable and state model. Conversion: Transfer function from
state equation, State equation to Transfer function. Solutions of state
equations, Controllability and Observability.
