| Description
An introduction
to automatic control systems, using classical control methods in the frequency
domain. Classical stability and performance analysis methods include the
root locus as well as the Bode and Nyquist diagrams. Control design will
be introduced based complex plane and frequency performance specifications.
Prerequisites
- understanding
of modeling and dynamic response,
- linear
differential equations,
- Laplace
transform.
Course
Aims
Introduction
to
- Linear
control systems
- Stability
analysis techniques
- Control
system performance
- Feedback
control design
By the end
of the course students should be able to
- interpret
and switch between differential equation and tranfer function system
representations
- relate
the time response to transfer function characteristics
- understand
stability and time domain specifications
- conclude
about stability using a variety of analysis tools
- design
PID controllers and understand the effect of their components
- draw and
interpret root loci, Nyquist and Bode diagrams
- design
feedback controllers in frequency domain.
