This project aims to develop a Combined Environments, Multiple-Input/Multiple-Output (MIMO) vibration
4
+
controller that can better simulate dynamic environments than a traditional single-shaker test.
5
+
6
+
The controller is nicknamed "Rattlesnake," which blends together snakes (as it is written in Python programming language),
7
+
vibration (rattlesnakes are famous for shaking their tails to create sound),
8
+
and New Mexico (the location of the main Sandia National Laboratories campus, where rattlesnakes can commonly be found).
9
+
10
+
Rattlesnake can be run as a Python script using the code from this repository, or an executable can be downloaded from the [Releases](https://github.com/sandialabs/rattlesnake-vibration-controller/releases) page.

### Flexible
15
+
16
+
The controller can currently run using National Instruments hardware using the [NI-DAQmx](https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P8baSAC&l=en-US)
17
+
interface or [B+K LAN-XI](https://www.bksv.com/en/instruments/daq-data-acquisition/lan-xi-daq-system) hardware using their OpenAPI.
18
+
It can also run synthetic control problems using finite element results or State Space Matrices. Advanced users can implement new hardware devices in Rattlesnake.
19
+
20
+
### Capable
21
+
22
+
Rattlesnake has been run with over 50 control channels and 12 shaker drives while streaming over 250 channels to disk.
23
+
24
+
### Research Focus
25
+
26
+
To facilitate MIMO vibration research and development, users can program their own control laws to load into the controller at runtime.
27
+
See [Control Laws](https://github.com/sandialabs/rattlesnake-vibration-controller/tree/main/control_laws) for examples.
