# CONTROL ENGINEERING - 2023/4

Module code: EEE3005

## Module Overview

Expected prior learning:  Module EEE2033 – Electronics III: Circuits, Control and Communications or equivalent learning.

Module purpose:  Control Engineering covers classical control theory as well as more modern methods. Students have the opportunity in this module to evaluate and apply various control techniques. This module builds on basic concepts previously introduced in Electronics III: Circuits, Control and Communications EEE2033, or equivalent learning and builds the fundamentals for a subsequent career as a control engineer or systems engineer.

## Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate the learning outcomes. The assignment will assess the ability to learn about practical design of control systems.

Thus, the summative assessment for this module consists of:

• Assignment report due in week 9

• Online open book examination within 4 hour window

Any deadline given here is indicative. For confirmation of exact date and time, please check the Departmental assessment calendar issued to you.

Formative assessment and feedback

For the module, students will receive formative assessment/feedback in the following ways.

·         During face-to-face sessions, by question and answer sessions·

·         By means of unassessed tutorial problem sheets (with answers/model solutions)

·         Via the marking of written reports

·        Via assessed coursework

## Module aims

• Students will have the knowledge to understand control system analysis and design, including state-space and sampled-data analysis, and to apply the techniques to a practical problem using Matlab.
• The module also aims to provide opportunities for students to learn about the Surrey Pillars listed below.

## Learning outcomes

## Methods of Teaching / Learning

The learning and teaching strategy is designed to achieve the following aims:

The strategy is designed to give students an understanding of basic concepts in control engineering, and also to learn how to analyse and model control systems using MATLAB.

Learning and teaching methods include the following:

• Online pre-recorded lecture content supported with face-to-face in class problem solving sessions. Sessions will employ a flipped class approach in which students attempt problems beforehand and then discuss their solution in class.

• Coursework:  Report on a tutorial sheet that requires use of MATLAB modelling software (alternative assignment is literature-based survey report).

• Tutorial presentation in class.

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.

## Other information

This module trains the student on the use of advanced control engineering concepts with a key focus on designing systems for realising different performance/response criteria. The module will also train the student on the use of MATLAB as a tool for problem solving in Control Engineering which will improve their Digital Capabilities and bring the final skills attained in line with current industrial expectations. Further, the Resourcefulness and resilience of students will be improved based on a number of challenges/problems which will be given to solve in groups or individually throughout the semester.  The above characteristics taken together is expected to improve the Employability of students who will be taking up this module and aiming to build their careers as Control Engineers or System Designers.  While Sustainability is less likely to be addressed during this course, the concepts learnt during this module are applicable for sustainable practices.
