Quarc Library Simulink ((install)) Jun 2026

Drag an block to capture encoder or analog sensor data.

What sets QUARC apart is its ability to generate real-time code directly from a Simulink block diagram without requiring users to write a single line of handwritten code. The same Simulink model used for offline simulation can be compiled, deployed, and executed in real-time on physical hardware—often with just a single click. This workflow dramatically reduces the development time for real-time control applications and lowers the barrier to entry for students and professionals alike.

In modern control engineering, bridging the gap between theoretical mathematical models and physical hardware is a crucial hurdle. is a premier software platform designed specifically to bridge this gap, allowing engineers and researchers to convert MATLAB/Simulink models into real-time applications without writing manual code . At the heart of this power lies the QUARC Targets Library , a specialized set of Simulink blocks that allow for hardware-in-the-loop (HIL) testing, rapid control prototyping, and advanced data acquisition.

Allows you to change block parameters (like PID gains) while the code runs on the target hardware. quarc library simulink

The HIL blocks allow you to interface with data acquisition boards (DAQ) instantly. You can read encoders, write to PWM outputs, and sample analog sensors by simply dragging and dropping blocks. 🟢 Universal Communications

Always place this at the top level of your model to define your hardware parameters globally.

The QUARC library seamlessly integrates into Simulink, transforming your block diagrams into real-time applications with just a few clicks. No more manual coding for hardware I/O or real-time scheduling. Drag an block to capture encoder or analog sensor data

The QUARC library for Simulink is a powerful and versatile tool for anyone looking to move control algorithms from the theoretical realm to physical implementation. Its comprehensive block library, robust real-time performance, and unmatched integration with the Simulink environment make it an ideal choice for both educational labs and advanced research projects. By abstracting away the complexities of real-time programming, QUARC allows engineers and students to focus on what truly matters: designing better control systems.

The most critical block in any QUARC model. It configures the global parameters of your target hardware (e.g., Quanser Q8-USB, Q-PID, or NI cards), setting up encoder channels, analog ranges, PWM frequencies, and initial/final output states.

When you open the Simulink Library Browser after installing QUARC, you will find several primary sub-libraries. Each serves a specific purpose in system development. This workflow dramatically reduces the development time for

Turn Simulink models into runnable controllers instantly.

With the model configured, building and deploying is remarkably simple. Starting with MATLAB R2021b, QUARC has its own dedicated tab in the Simulink toolstrip with buttons for building, deploying, and controlling the real-time executable. Clicking “Monitor & Tune” builds the model, generates C/C++ code, compiles it, downloads it to the target, and starts execution—all automatically.
