PhD: Novel Sensors For Electric Actuators and Propulsion Drives

University of Bristol - Electrical and Electronic Engineering

The project:

This PhD will focus on developing a rigorous understanding of the operation of state-of-the-art existing generators across a range of domains (mechanical, electrical and thermal). Adding “smart” functionality to these machines requires models that can inform control systems of the operating regime, predict lifetime and failures and adapt to changes in requirements in near real-time. The successful candidate will be involved in developing a series of these models based upon a combination of finite-element analysis and experimental testing.

This is an integral part of increasing the presence and impact of electrical technologies in civil airliners and will also result in:

  • weight and/or volume reduction through performance optimisation
  • reduced maintenance and through-life costs
  • improved functionality (intelligent operation/actuation)

The first part of this PhD will focus on ways of measuring machine quantities such as:

  • stator and rotor voltages and currents
  • component temperatures

whilst the machine is in operation, rotating at speeds.

The second aspect will look at ways in which the data that is being captured can be used to add intelligence to the controller associated with the machine to improve its operation and reliability in service and to assist system design optimisation. This will focus on developing a series of adaptable, lumped parameter, electro-thermo-mechanical models that can be implemented in a discrete form on a real-time architecture. Validation of the models will be performed using existing production hardware, modified and instrumented as necessary.
