Module Description: This module aims to introduce concepts of modelling and control design for engineering systems. The approach is to present an engineering methodology that, while based on mathematical fundamentals, stresses physical systems modelling and practical control systems design with realistic system specifications. It aims to study the performance, characteristics and advantages of feedback control systems, and to introduce control design techniques based on steady state and transient response specifications.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Explain the fundamental concepts,terminology and purpose of control engineering.
LO2 Compose dynamic, continuous time mathematical models of various physical systems using differential equations and Laplace transform methods.
LO3 Analyse the time domain transient and steady state response of zero, first and second order systems.
LO4 Assess the stability of closed loop systems by means of the root location in s-plane and their effects on system performance.
LO5 Design controllers to modify the response of negative feedback control loops to meet criteria using analytical and graphical methods in the time and Laplace domains.
LO6 Construct root loci and use them to evaluate the effect of parameter variation on system dynamics.
LO7 Undertake open and closed loop control of a DC motor servo for speed and position control using PID methods.
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).
