Description

The purpose of this module is to enable students to develop a knowledge of: system stability using frequency response methods; disturbance rejection; steady-state error analysis and design, system performance analysis and measurement, control system design and analysis for continuous systems using classical techniques. Students will attain skills in using software tools to represent, analyse, interpret and design control 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 and design for steady-state error requirements
3. analyse system stability and performance using analytical techniques
4. analyse system stability and performance using graphical frequency response techniques
5. design, simulate and evaluate compensator-based control schemes
6. design, simulate and evaluate PID-based control schemes
7. use appropriate software tools to present, analyse, design and simulate systems
8. effectively present and discuss the analysis and/or design of systems by written means

Indicative Content and Learning Activities

CONTROL SYSTEMS SOFTWARE TOOLS
Introduction to software for control systems analysis, simulation, design and evaluation, 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?

STEADY-STATE ERROR
What is steady-state error and what does it depend on? What are system types and what are input types? How are expressions for error derived, and how can the steady-state error be established? How can systems be designed to give minimum or specified steady-state error performance?

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 analyse and design for system performance?

COMPENSATOR-BASED CONTROL DESIGN
What are frequency-response-based compensators? What types of compensators are commonly available and how should a compensator be chosen? How do these compensators behave within feedback systems? How can these compensators be designed to give specified closed-loop performance?

PID-BASED CONTROL DESIGN
Why are controllers other than simple gain controllers required? What are integral and derivative control, and what are the benefits and drawbacks of these techniques. How can PID controllers be designed using classical techniques and how can these control schemes be simulated and evaluated?

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
This module is category 1
