All Module information is indicative, and this portal is an interim interface pending the full upgrade of Coursebuilder and subsequent integration to the new DCU Student Information System (DCU Key).

As such, this is a point in time view of data which will be refreshed periodically. Some fields/data may not yet be available pending the completion of the full Coursebuilder upgrade and integration project. We will post status updates as they become available.

Description

The purpose of this module is to enable students to develop a knowledge of: system stability using frequency response methods; disturbance rejection; nonlinear frequency response, basic feedback control for continuous and discrete-time systems. Students will attain skills in using software tools to represent, analyse, interpret and design system responses. This module is delivered in both on-campus and distance learning modes and students can avail of either or both modes to suit their own learning needs. Students are expected to engage in lectures and other module activities in either or both modes.

Learning Outcomes

1. calculate system sensitivity and disturbance rejection and the effect of feedback on these
2. analyse system stability and performance using graphical frequency response techniques
3. analyse the behaviour of nonlinear elements using graphical frequency and state-space response techniques
4. design, simulate and evaluate a basic feedback control system
5. use appropriate software tools to present, analyse, design and simulate systems
6. effectively present and discuss the analysis and/or design of systems by written means

Indicative Content and Learning Activities

MATLAB & SIMULINK / SCILAB & SCICOS
Introduction to MATLAB & SIMULINK or SCILAB & SCICOS and the use of appropriate software toolboxes to address the design and analysis needs of the module.

SYSTEM SENSITIVITY
What are sensitivity functions and how is sensitivity to errors in forward path, feedback path and frequency dependence calculated? What is disturbance rejection? What are physical examples of disturbances? How are transfer functions between disturbance and output calculated and used? How does the frequency affect disturbance rejection?

FREQUENCY RESPONSE FOR STABILITY & PERFORMANCE
What is a Bode plot? What is a Nyquist plot? What is the Nyquist criterion? What is relative stability? How can frequency response plots be used to determine system stability? What is bandwidth? How can time-domain performance be represented in the frequency domain? How can frequency response techniques be applied to discrete-time systems?

FEEDBACK CONTROL DESIGN
What is steady-state error? How can feedback control effect this error? How can a frequency response plot be used for basic feedback control design?

NON-LINEAR SYSTEMS
What are common types of non-linearities? How can describing functions for non-linearities be derived? What is limit cycle stability and how can it be used in describing function analysis? How can phase-plane analysis be applied to linear and non-linear systems?

Reassessment Requirement Type
Resit arrangements are explained by the following categories: Resit category 1: A resit is available for both* components of the module. Resit category 2: No resit is available for a 100% continuous assessment module. Resit category 3: No resit is available for the continuous assessment component where there is a continuous assessment and examination element.
* ‘Both’ is used in the context of the module having a Continuous Assessment/Examination split; where the module is 100% continuous assessment, there will also be a resit of the assessment
