Description

The Systems and Control Engineering course introduces students to the basic methods of Automatic Control engineering, i.e. for continuous-time single-input/single-output linear systems, and to the methods of modelling associated plant dynamics. The Vibrations course is designed to teach basic vibration phenomena, such as how vibration is caused, how it is measured, and what its consequences are. The single degree of freedom mass-spring-damper system is analysed, both in free vibration and with various forms of excitation. The importance of resonance and force transmission is stressed. Students should gain an understanding of natural frequencies and how these relate to free and forced vibration, together with vibration transmission. They will also learn about multi-degree of freedom systems in free and forced vibration and how to apply numerical methods of solution. The laboratory class illustrates aspects of the course, especially resonance and damping and the behaviour of systems with two degrees of freedom.

Aims:

Systems & Control Engineering:

To introduce students to the basic methodologies of modelling dynamic systems and controlling them. The methodology of using Laplace transforms to derive transfer functions is applied to learn how to design controllers for single-input-single-output dynamic systems.

Vibrations:

This course is designed to teach basic vibration phenomena, such as how vibration is caused, how it is measured, and what its consequences are. The single degree of freedom mass-spring-damper system is analysed, both in free vibration and with various forms of excitation. The importance of resonance and force transmission is stressed. The laboratory class illustrates aspects of the course, especially resonance and damping, and the behaviour of systems with two degrees of freedom.

Intended learning outcomes

Systems & Control Engineering:

By the end of the course students should be able to:

  • Derive equations to model the dynamics of one and two degree of freedom (DOF) systems.
  • Use Laplace Transforms to derive system transfer functions
  • Classify and implement control strategies for single-input-single-output linear systems

Vibrations:

  • Identify and characterise natural frequencies and analyse how they relate to free and forced vibration, together with vibration transmission.
  • Classify and derive equations to model multi-DOF systems in free and forced vibration and apply numerical methods of solution.

Teaching details

Systems & Control Engineering:

Students receive one 1-hour lecture each week over 24 weeks. The course lectures are supported by use of MATLAB/SIMULINK computer simulations of dynamic systems. There is a practical laboratory experiment using 3-DOF helicopters.

Vibrations:

Students receive one 1-hour lecture each week over 24 weeks. In addition, there is a 2-hour laboratory class.

Assessment Details

There is a 3-hour written examination, 4 questions from 6 (90%). In the written examination, 2 questions from 3 are from the Systems & Control Engineering course (LOs 1-3) and 2 questions from 3 are from the Vibrations course (LOs 4-5). During the Systems & Control Engineering course, marks for one piece of laboratory work are incorporated into the end of year unit assessment (5%) (LO 3). During the Vibrations course, marks for laboratory work are incorporated into the end of year unit assessment (5%) (LO 4).
