Overview

The Moku:Pro PID Controller features four fully configurable PID controllers. 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.[/lq_Video_image_text_top_bottom]

Block diagram view of the DSP workflow

Four independent, fully real-time configurable PID controller paths follow the control matrix in the block diagram, making it so easy to use that you can do it in the dark (mode).[/lq_image_text][lq_image_text image=”7973″ image_position=”Right”]

PID response plot

An interactive representation (gain as a function of frequency) of the controller, the PID response plot makes it easy to adjust your configurations and see the changes in real-time.[/lq_image_text][lq_image_text image=”7948″]

Available on Moku:Pro hardware

Our most powerful hardware platform to date, Moku:Pro harnesses the power of a Xilinx Ultrascale+ FPGA with higher bandwidth, lower noise, more channels, and more output power than ever before.[/lq_image_text]
