EE312_ Control System Engineering_Moodle_Page

Welcome to EE312: Control System Engineering
This course builds on the fundamentals of calculus and signals and systems. It is structured as a first
course in control systems engineering. The course provides sound knowledge of the devices and
components used in process control and instrumentation. It also provides an understanding of the
fundamental principles of process dynamics and feedback control. Topics to be covered include
introduction to control, mathematical modelling of control systems, transducers (sensors), actuators,
system performance and specifications, and design of controllers using classical control techniques. It
provides the foundation for further course on digital control systems.

Projects
A PLC is a specialised form of a digital computer that is optimised for the implementation of
relay logic type of circuits. PLCs are widely used in automation (sequential control) systems.
In these mini-projects you will design and test an OMRON PLC based controllers for traffic
light systems, burglar alarms, water tank monitoring systems, and game systems. The
specifications of the system are given in Section A. Section B gives details of the mini-project
submission requirements and the assessment criteria.
The specific objectives of this project are to:
Design and test controllers for physical systems.1.
Function as an individual, and as a member or leader of a team.2.
Produce written reports and oral presentations of practical work.3.
Apply project management techniques to the planning and execution of future work.4.
Each group is required to submit a technical report (refer to http://www.monash.edu.au
/lls/llonline/writing/engineering/technical-report/index.xml for more information about
technical reports) and give a 20 minute presentation of their work.

The purpose of this exercise is to give you a quick hands-on introduction to using SIMULINK
and MATLAB to simulate the response of a control system model. In particular at the end of
the exercise you should be able to:
Build a simple block diagram model of a control system using SIMULINK & MATLAB.
Simulate the block diagram model in SIMULINK & MATLAB and display the
simulation results in graphical form on the computer screen.
Analyze the results of the simulation using MATLABS LTI Viewer and also using your
knowledge of system performance and specifications.
