Single-Axis Piezo Nanopositioning Controllers
The resolution, stability and performance of a piezo nanopositioning controller directly influence the accuracy of the complete nanopositioning system. Digital servos are useful when high positioning linearity, software configuration and changing load conditions are important. Analog servos can provide low noise, fast response and attractive cost when the application does not require extensive digital optimization.
PI piezo nanopositioning controllers are available for strain gauge and capacitive feedback systems, OEM integration, bench-top operation, modular rack systems and high-power piezo actuator drive applications.
