The rotor mass imbalance and sensor runout will cause the harmonic vibration of active magnetic bearing system. Repetitive control (RC) can effectively eliminate periodic disturbances. When the ...

A novel vibration sensor based on the single mode (SM)-no core (NC)-SM fiber structure is proposed and experimentally sensing results demonstrated. By numerical simulation, we use an NC fiber (NCF) as ...

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for super cheap, and they're incredibly versatile. When you're done using an ...
