PID Controller

With the Moku PID Controller, it’s easy to leverage up to four fully configurable PID controllers to simplify system feedback and stabilization. Deploy them in applications requiring both low and high feedback bandwidths, such as laser temperature and current stabilization. For maximum flexibility, you can also utilize the Moku PID Controller as a lead-lag compensator by saturating the integral and differential controllers with independent gain settings.

The Moku PID Controller is easy to use and offers a range of advanced capabilities to optimize your experiment — at the most cost-effective price in the industry.

View system responses in real time with the PID response plot

Quickly design your control system’s frequency response using the interactive Bode plot. With built-in Oscilloscope probe points for signal monitoring throughout the signal path, you can adjust parameters and view results simultaneously.

Customize your system response with an advanced multi-section PID builder

The Moku PID Controller includes single or double integrators and differentiators with low- and high-frequency gain saturation. Configure proportional (P), integral (I), differential (D), double-integral (I+), integral saturation (IS), and differential saturation (DS) gain profiles.

Test smarter with a block diagram view of the DSP workflow

Enable up to four independent, fully real-time configurable PID controller paths. For even more flexibility, you have the option to combine input signals with the control matrix.

Run multiple instruments simultaneously in Multi-instrument Mode

Four controllers isn’t enough? Get up to eight independent controllers by deploying multiple Moku PID Controllers in Multi-instrument Mode. Route connections to the analog inputs and outputs, or digitally connect instruments together for lossless instrument cabling.

Engineered to work seamlessly with your favorite APIs

API integration with MATLAB, LabVIEW, and more allows straightforward automation of your Moku device in complex setups or for repetitive tasks. Save your measurements, screenshots, traces, and other settings locally or to your preferred cloud app. You can also send work to yourself or colleagues within the Moku app.

Engineered for demanding applications

You can’t innovate for the future when your test equipment is stuck in the past. Use the Moku PID Controller to accelerate development timelines with speed and flexibility unmatched by any other instrument in its class.
