PhD Studentship: Active Vibration Control using Nonlinear Electrical Damping

University of Southampton

Project Reference: ISVR-SPCG-123

Project Themes: Mechatronics, signal processing and control

This project will involve the development of nonlinear control strategies such as nonlinear electrical damping for vibration control and energy harvesting.  Theoretical work involves implementing electrical damping in the form of on-off, impulsive, polynomial and other nonlinear forms to achieve better performance in vibration control. Both numerical and analytical simulations will be carried out to obtain the response. Experiments will be carried out to validate the theoretical developments.  The nonlinear electrical damping can be achieved using programmable resistive load. In addition, an appropriate design of an electrical circuit will be considered to control both damping and frequency. Potential exploitation of nonlinearity in the design of energy harvesters will also be investigated.
