Module Overview

This module provides students with an understanding of the tools & techniques required to interface between mechanical components and the wider world, involving sensing, actuation (e.g. motors) modelling and control.

Topics Covered

Modelling Dynamic Systems

  • Time-response (“dynamics”) of first- and second-order systems: including examples of electrical filters used to reduce ripple & electrical noise.
  • Ordinary differential equations (ODE), to complement (not duplicate) the Mechanics of Solids and core IEP modelling & analysis syllabus.
  • Mass-spring-damper systems and the concepts of resonance.

Instrumentation

  • Measures of strain (strain gauge), displacement (optical encoder, LVDT, possibly hall-effect sensor), force, velocity, temperature.

Control and Electrical Power

  • Introduction to control. Open- and closed-loop control representation, emphasising open loop = “model-based predictive control”. Examples of regulation, including cruise control (speed), temperature control.
  • Feedback, and the general structure of a control loop.
  • Electric motor types, including impedance.

Learning Outcomes

Upon completion of this module students will be able to:

  • Create linear analytical models of dynamic systems and solve them to identify the response of those systems to a range of inputs.
  • Select appropriate sensors which may be required to interface between a mechanical system and its application (e.g. displacement sensor).
  • Identify the important components of a control loop and choose a general control strategy.
  • Analyse a range of electrical power machines and identify their suitability for applications.

Method of Instruction

This module is taught through:

  • Lectures
  • Practical laboratory classes

Assessment

This module is assessed through a combination of unseen written examination and coursework exercises.
