Spectral decomposition for fast servo control

Chatsworth, California – Delta Tau now offers a new control method called Spectral Decomposition to improve the productivity of systems that use fast-tool actuators.

 

Spectral decomposition works with a variety of fast-tool actuators – including voice-coil motors, piezo crystals, laser galvanometers and magnetostrictive transducers. These actuators have high bandwidth, but limited travel. So they're typically paired with a standard servo for longer-range positioning moves.

 

Spectral decomposition coordinates the trajectories of fast-tool actuators and positioning servos, including in complex multi-axis systems, for typical cycle time reductions of 25%.
