Overview

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

Monitor the behavior of the PID controller in real time

With all-digital implementation, you can monitor the signal before and after the PID controller in real time with the built-in oscilloscope. Any adjustment on the controller parameters reflects on the output in real time. No additional test and measurement equipment is required to monitor the system response.[/lq_image_text][lq_image_text image=”5374″ image_position=”Right”]

Interactive PID configurator

The Moku:Go PID configurator allows you to design the PID by gain (Ki, Kp, Kd) or frequency (Kp, integrator, and differentiator crossover frequencies) profiles. You can directly drag the cursors on the interactive Bode plot to shape the frequency response of the controller. All design methodologies allow you to set low- and high-frequency saturation.[/lq_image_text][lq_image_text image=”7630″]

Available on Moku:Go hardware

A powerful FPGA paired with a high-quality analog front-end make Moku:Go the most robust hardware in education, capable of complex, real-time digital signal processing. An integrated Wi-Fi hotspot and programmable power supplies ensure that students have the complete solution they need all four years (and beyond).[/lq_image_text]
