Vibration isolation and control of sensitive systems

Thursday, January 7, 9:00am
Marlar Lounge (37-252)

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
- Damping
- Transmissibility and compliance
- Multi-staging
- 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.
