Title:Control Eng. and Automation
Long Title:Control Eng. and Automation
Module Code:MECH8001
Duration:1 Semester
Credits: 5
NFQ Level:Advanced
Field of Study: Mechanical Engineering
Valid From: Semester 1 - 2016/17 ( September 2016 )
Module Delivered in 1 programme(s)
Module Coordinator: GER KELLY
Module Description: This module is organised around the concept of control systems theory as it has been developed in the frequency domain. It provides coverage of classical control, frequency and response design using Bode and Nyquist plots. The application to Process control is included. Digital and non linear methods are examined. Incorporates computer-aided design and analysis using Matlab and Simulink.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Interpret the open loop frequency response with regard to stability and performance using graphical methods such as the Bode and Nyquist plot.
LO2 Design controllers to meet desired specifications using frequency response methods.
LO3 Analyse certain non-linear systems using describing functions.
LO4 Investigate sampled-data systems and discrete time models by means of root loci and Bode plots using the open and closed loop transfer functions in the Z-domain.
LO5 Evaluate various process control strategies for the safe and efficient operation of various process applications (e.g. level, pressure, flow and temperature control).
LO6 Select amongst graphical, written, computer simulation and mathematical models the most appropriate methods to aid the design and communicate the preformance characteristics of various dynamic systems.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
