Multi-Shaker Vibration Controller
The Data Physics 800 Series is a Feature-Rich MIMO Vibration Controller Developed Around Mil-810 Method 527 that Adapts to Any Multi-Shaker Configuration
The 800 Series controller can reproduce any type of vibration – with 2-16+ shakers configured in any arrangement. It is a true MIMO controller – which means it can control setups with different amplifiers and shakers, off-center masses, and accounts for structural resonances in its control loop – Matching amplifiers/shakers or centering the moving mass is not needed.

- Ideal for 3- or 6- DoF road or air transportation simulations
- Enter profiles as Translations/Rotations about a center, as translations at sensor locations, or a combination
- Control Nulling – Null vibrations in a particular axis or at a specific location
- Real-time FRF updating, or stored FRF
