PID Controller

Moku:Pro User Manual

Moku:Pro’s PID (Proportional-Integrator-Differentiator) Controller features four fully real-time

configurable PID controllers with a closed-loop bandwidth >100 kHz. This enables them to be used

in applications requiring both low and high feedback bandwidths such as temperature and laser

frequency stabilization. The PID Controller can also be used as a lead-lag compensator by

saturating the integral and differential controllers with independent gain settings.
