# CONTROL - 2024/5

Module code: ENG2123

## Module Overview

Control and its application spans across all areas of engineering and beyond. Examples of control systems can be found in automotive, biomedical, aerospace and mechanical engineering. Furthermore, industrial automation leverages control systems to improve efficiency, quality, safety while reducing production costs. This control module introduces to students foundational concepts in control engineering and provide methods for analysing linear dynamic systems and linear control systems that can be applied to different engineering domains. This module gives to students also the foundation for the design of standard control solutions.

## Assessment pattern

Assessment type Unit of assessment Weighting
Online Scheduled Summative Class Test Online Test (1 hour) 20
Examination Closed Book Exam (2 hours) 80

None.

## 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  system analysis and 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]

The Formative assessment consists in active discussion during the lectures and tutorials, either triggered by the module conveyer or directly by the student. Moreover, tutorials solutions are provided after tutorial sessions.

Feedback is given verbally via weekly supported tutorial work.

## Module aims

• Expose students to a systematic understanding and critical awareness of the importance of control in engineering;
• Provide students with the knowledge of how to analyse linear dynamic systems;
• Provide students with the knowledge of techniques used to analyse linear and time-invariant control systems;
• Equip students with an understanding of transform methods for solving engineering problems.

## Methods of Teaching / Learning

The learning and teaching strategy is designed to familiarize students with the methods for the analysis of linear dynamic systems and linear control systems, as well as the design of basic standard controllers. This is attained by combining theoretical instruction and practical application by using worked examples. The primary methods of delivering this strategy involve lectures (supported by captured content) and tutorial sessions.

The learning and teaching methods include:

• Lectures (supported by captured content) aim to present and enable discussion on fundamental topics, methods and theories.

• Tutorials provide students with an opportunity to review and strengthen their grasp of concepts covered in lectures. By working collaboratively in groups, students can actively participate in discussions, inquire questions, and grow their comprehension of the subject.

• Guided Learning provide students with an opportunity to consolidate methods and theories.

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.
