SESM3030 Control and Instrumentation

Module Overview

This module covers the topics on classical and modern control analysis and design, focuses on feedback control approaches using state-space (differential equations). It discusses deeply the analysis and design for continuous-time linear time invariant (LTI) systems. As nonlinearities are often inevitable in applications, this module also introduces the analysis and design for nonlinear dynamical systems, mainly using the Lyapunov approach. The practical aspects of control design and its digital implementation are discussed in this module. This will cover the introduction to digital control and the fundamental of signal processing and instrumentation, which includes data acquisition, sensors and actuators. The course aims to give the student a general overview of instrumentation systems, with particular emphasis on the integration of the various components. The course will require a basic understanding of electronics, to include operational amplifiers and digital electronics. To attend this module, students are expected to have learned and understood the classical continuous-time control analysis and design that include dynamical modelling, transient responses, stability and steady state error analysis, at least in frequency domain and the 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: 1. In frequency domain using Nyquist stability test and 2. In time domain using the eigen value analysis
  • Perform the following controller designs: 1. lead-lag compensators, 2. state-feedback controllers and observers.
  • Analyse the dynamic behaviour nonlinear systems, do the stability analysis and design based on Lyapunov approach
  • Transform continuous-time dynamics into discrete-time dynamics for control purposes, and perform discrete-time control analysis/design based on their analogy to continuous-time methods.
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
  • Gain skills in applying various control analysis and design tools into real applications through taught control examples and in the coursework.
