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.

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 simple system
  • Use Laplace Transforms to derive transfer functions
  • Implement control strategies for single-input-single-output linear systems

Vibrations:

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.

Teaching details

Systems & Control Engineering:

The course lectures are backed-up by extensive use of MATLAB/SIMULINK computer simulations of dynamic systems and practical laboratory experiments using 3DOF-helicopters.

Vibrations:

Students receive two 1-hour lectures each week over 12 weeks. In addition, there is a 2-hour laboratory class.

Assessment Details

There is a 3-hour written examination, 4 questions from 6. (85%) During the Systems & Control Engineering course, marks for two pieces of laboratory work are incorporated into the end of year unit assessment (10%). During the Vibrations course, marks for laboratory work are incorporated into the end of year unit assessment (5%).
