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 (鈥渄ynamics鈥�) 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 = 鈥渕odel-based predictive control鈥�. 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.
