Technical note: piezo controller thermal stability comparison

Piezo controller design can have a significant effect on thermal stability causing excessive error in precision motion applications. In this technical note, we briefly describe some techniques used for controlling thermal effects and compare the thermal stability of our piezo control electronics with a competitive design.

Thermal stability is paramount in any precision process. Thermal drift of mechanical and electrical components can cause errors that far exceed any tolerance stackup of components or positioning errors of motion equipment used in that process. There are three common ways that designers can manage thermal effects in precision machinery and instrumentation…
