Shaft-mounted vibration control systems in rotating machinery Samuel Jiménez Prof P. Keogh, Dr Matt Cole University of Bath UKACC PhD Presentation Showcase

Rotor vibration management Vibration control over a range of operating conditions Active control systems Current technology Eddy current displacement sensors Rotor Turbine blades Active magnetic bearing actuator UKACC PhD Presentation Showcase

Improved observability and My research Aim: Improved performance of active systems Shaft-mounted designs Advantages vs. current designs Increased number of active components Freedom to locate components Develop sensors/actuators which operate inside a rotating shaft Improved observability and controllability UKACC PhD Presentation Showcase
