Autonomous Switching Shunts

A completely autonomous shunt circuit was developed and implemented. It does not require any power for operation and its size is tiny. Experiments showed a vibration suppression of around 60%-70%.

The described shunt circuit is based on so called Switching Shunts. An optimal switching law was derived using the Hybrid System Framework. The obtained switching law was implemented with a few analog electronic components, such that the resulting circuit does not require power for operation. Additionally, the circuit can tune itself automatically [1].
