PID Controller

For more information on the Moku Go, Pro and Lab series specifications and applications visit the blog “Are you looking to combine your laboratory into one portable Moku Lab?” or download the datasheets from the download tab.

Moku:Go’s PID Controller instrument features two fully configurable PID controllers with an output sampling rate of >2.5 MSa/s. This enables them to be used in various applications such as current or robotic arm control. The intuitive graphic user interface allows you to directly adjust the PID parameters on the Bode plot. Users are able to monitor the effects of the change with the built-in oscilloscope in real-time, which makes Moku:Go‘s
PID the best tool for control system labs.

Moku:Lab’s PID Controller features two fully configurable PID controllers with an output sample rate of 10 MSa/s. This enables them to be used in applications requiring both low and high feedback bandwidths such as laser temperature and current stabilization. The PID Controller can also be used as a lead-lag compensator by saturating the integral and differential controllers with independent gain settings.

Moku:Pro’s PID Controller features four fully configurable PID controllers with sub-microsecond latency. This enables them to be used in applications requiring both low and high feedback bandwidths such as laser temperature and current stabilization. The PID Controller can also be used as a leadlag compensator by saturating the integral and differential controllers with independent gain settings.
