Active Noise and Vibration Control
The Acoustics, Vibration and Control (AVC) Group was established in 1987 with a grant from the Sir Ross and Sir Keith Smith fund for fundamental studies leading to a system to actively control aircraft cabin noise. The results from fundamental research in active noise and vibration control has led to the development of commercial controllers and to the installation of practical systems in industry.
Examples of our work include:
- Adaptive exhaust silencer for diesel engines
- Adaptive tuned vibration neutraliser
- EZ-ANC II active noise and vibration controller
- Development of an adaptive Helmholtz resonator for industrial exhaust stacks
- Active vibration control of gearbox vibration
- Active control of fan noise in a high temperature exhaust stack
- Physical system optimization for the active control of electrical transformer noise
- Active noise control inside a launch vehicle payload bay
- Synchrophasing two axial fans in a duct
- Nonlinear dynamics and control of magnetic bearing systems
