Vibration isolation and control of sensitive systems
Vibration isolation and control of sensitive systems - 2 hours
Activity Leader: Fabrice Matichard, Visiting Research Scientist
The presentation will give a general introduction to the problem of vibration isolation. We'll discuss the following concepts:
- Passive isolation principles
- Static deflection
- Transmissibility and compliance
- Active isolation principles
- Block diagrams
- Loop shaping
- Absolute versus relative control
- Inertial sensors
- Sensor Noise
- Sensor Fusion
- Noise Budgeting
- Feedforward control
We'll finish the presentation by a review of vibration isolation systems used either in the industry or in physics experiments.
Presentation 9:00-11:00 in Marlar Lounge 37-252. A tour of the LIGO labs will follow the presentation. Pre-requisite for taking the LIGO labs tour is attending the presentation.
Requirements: basic knowledge of Laplace/Frequency domain formalism.
Presentation and tour limited to 16 people. Advanced sign up required by 4pm on January 6.
