# CONTROL - 2022/3

Module code: ENG2123

## Module Overview

Second year common module in control for MES students.

Control in its application spans across all areas of engineering and beyond. This module provides fundamentals of linear, time-invariant control system analysis in both time and Laplace domain, as well as respective controller design.

## Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

understanding of scientific principles, methodologies and mathematical methods associated with control systems as well as the ability to analyse and design particular systems in the final examination. The inter-semester test amplifies awareness and ability to devise control concept and to analyse systems from their response.

Thus, the summative assessment for this module consists of:

• In-semester test [Learning outcomes 2, 3]

• Examination [Learning outcomes 1, 3, 4, 5]

Formative assessment and feedback

• Formative verbal feedback is given in tutorials.

## Module aims

• A systematic understanding and critical awareness of the importance of control in engineering;
• A knowledge of dynamic system analysis;
• A knowledge of the techniques used to design linear and time-invariant control systems;
• An understanding of transform methods for solving engineering problems.

## Learning outcomes

 Ref Attributes Developed 001 Upon successful completion of the module, students will be able to: provide, identify and compose: the specification of the dynamics and control requirements of systems; the general concept, the types and the structure of control hardware; K C13 002 Effectively interpret and employ definitions of common terms including feed-forward, feedback, linear and non-linear models, and time and Laplace domain; KP C1 003 Select and use appropriate Laplace Transform techniques and results in solving control problems and initial value engineering problems; K C1, C2 004 Formulate simple dynamic models rigorously, tune a controller using simple rules, employ Laplace transform and represent dynamics as block diagrams; C C3 005 Recognise the importance and relevance of process dynamics and control, especially the behaviour of linear, time-invariant and single loop feedback systems.

## Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Introduce principles of control systems analysis and design through theory and worked examples. This is mainly delivered through captured content lectures and tutorial classes with independently worked out examples.

The learning and teaching methods include:

• Tutorials (in groups)

• Lectures

• Captured content

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
