How do Controllers work?
Controllers for piezo-systems interact between actuators, sensors and users:
Digital controllers allow for easily adapting and optimizing control parameters (PID, notch-filters) and exchangability of connected mechanics (ID-Chip). Such controllers are typically equipped with analog and digital interfaces – USB, Ethernet and RS232. Graphical user interfaces (GUI) provide examination features like oscilloscope (view step-responses, rest-noise, etc.) and FFT (see Bode-Plots of amplitudes and phases over frequency).
Example, open loop:
