SESM3030 Control and Instrumentation

Module Overview

This module covers topics in classical and modern control analysis and design with a focus on linear time invariant systems. Fundamental design and analysis in the time and frequency domain are reviewed and developed. The properties of discrete-time systems (computer control) are introduced and the fundamentals of digital control introduced. State-space control analysis and design methods are then explored, including multivariable control and disturbance rejection. As all systems are nonlinear to some extent, this module also introduces the analysis and design for nonlinear dynamical systems. The practical aspects of control design and its digital implementation are also discussed in this module. The module aims to give the student a general overview of instrumentation systems, with particular emphasis on the integration of the various components in a system. There is an emphasis on system design, such that students can design a complete system, from an understating of the measurement requirement to the input to digital systems. It includes an introduction to digital signal processing. The module will require/assume a basic understanding of electronics, to include operational amplifiers and digital electronics. To attend this module, students are expected to have learned and understood classical continuous-time control analysis and design that includes dynamical modelling, transient responses, stability and steady state error analysis and basic PID controller design.

Aims and Objectives

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

  • The mathematical modelling of dynamic, particularly electro-mechanical, systems.
  • The fundamentals of classical control design methods, to identify, classify and analyse the performance of systems and components through the use of analytical and computer based techniques
  • The principles of instrumentation and measurement systems, which demonstrates the ability to apply and integrate knowledge and understanding of other engineering disciplines to support the study of their own engineering discipline
Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

  • Analyse the stability of a system in the time and frequency domains.
  • Transform continuous-time dynamics into discrete-time dynamics for control and instrumentation purposes, and perform discrete-time control analysis/design based on their analogy to continuous-time methods.
  • Perform controller designs using lead-lag compensators and state-feedback.
  • Understand and analyse the behaviour of nonlinear systems using the phase-plane method and describing functions.
Transferable and Generic Skills

Having successfully completed this module you will be able to:

  • Judge the merits of using approximate state-space, frequency response and phase plane models to solve control problems
