Prerequisites / Co-requisites
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 frequency domain, as well as respective controller design.
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.

Process modelling: Concept, the transfer function and its characteristics, the system response from the transfer function, the block diagram and system simplification;
Linear system analysis in the time domain: Response of the first-order system, steady-state error, response of the second order system, system response versus pole location, response of the time-delayed systems;
Design of control systems in time domain: Closed loop vs. open loop systems, general requirements of control systems, automatic controllers (P, PI, PD and PID), tuning of PID controllers;
Sensors and actuators: Sensors, actuators, sensors in control systems, actuators in control 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 lectures and tutorial classes with independently worked out examples.
The learning and teaching methods include:
3 hours lecture per week x 11 weeks
1 hour tutorial x 11 weeks
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] (1 hr) (25%)
Examination [Learning outcomes 1, 3, 4, 5] (2 hrs) (75%)
Formative assessment and feedback
Formative verbal feedback is given in tutorials
Formative feedback on multiple choice tests are given verbally and available on SurreyLearn to provide feedback on understanding control systems analysis and simple design.
