Moku:Go’s PID Controller

Compare all PID controllers

Overview

Moku:Go’s 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. 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.

Monitor the behavior of the PID controller in real-time

With Moku:Go’s all-digital implementation, users 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.

Interactive PID configurator

Moku:Go’s 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.

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. Integrated WiFi hotspot and programmable power supplies ensure that students have the complete solution they need all four years (and beyond).

Moku:Go features a suite of eight instruments

Replace multiple instruments with a single device that has everything students need for a fraction of the cost.
