Study-Unit Description


CODE SCE2213

 
TITLE Automatic Control Systems 2

 
UM LEVEL 02 - Years 2, 3 in Modular Undergraduate Course

 
ECTS CREDITS 5

 
DEPARTMENT Systems and Control Engineering

 
DESCRIPTION Performance of Control Systems:
- Definition of stability and link between CLTF poles and stability;
- Routh Stability Criterion;
- Closed-loop system performance: System types, steady state errors, error constants, time domain specifications, sensitivity functions and noise rejection;
- Root-locus techniques.

Frequency Domain Analysis of Stability:
- Phase and Gain Margins from Bode plots;
- Nyquist Stability Criterion and Nyquist Plots;
- Nichols Plots.

Study-unit Aims:

This study-unit develops the concepts of classical automatic control theory introduced in SCE2111, concerning analysis of linear time-invariant feedback systems, with particular emphasis on stability using root-locus and frequency response techniques.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to, given the mathematical description of the linear dynamics of a system:
- explain the conditions of closed loop stability in both the time and the frequency domains;
- explain the system's closed loop behaviour for changing closed loop gain.

2. Skills:

By the end of the study-unit the student will be able to, given the mathematical description of the linear dynamics of a system:
- analyse the performance and stability of closed loop systems by mathematical methods;
- obtain root loci for the system's closed loop poles for changing open-loop gain;
- analyse the stability of closed loop system from frequency domain plots such as Bode, Nyquist and Nichols plots.
