Quarc Library Simulink [work] Online

The Quarc library has a wide range of applications in the development of control systems, including:

The real-time constraints (e.g., avoiding infinite loops, stack overruns) can trip users new to hard real-time systems.

The most critical block in any QUARC model. It configures your specific hardware board (e.g., Quanser Q8-USB, Q3 ControlpaQ) and sets initial, final, and safety watchdog voltages.

on various targets, including Windows and Linux, and allows for online parameter tuning directly from the Simulink diagram. Asynchronous Execution : Blocks like the Asynchronous Thread quarc library simulink

The adds specialized blocks to your Simulink Library Browser including:

Start by creating a Simulink model as you normally would for simulation. The model can include standard Simulink blocks alongside specialized QUARC blocks for hardware I/O, communications, or host device interaction. For hardware access, QUARC provides HIL (Hardware-in-the-Loop) blocks that read sensors and write actuator commands.

Set your safety parameters, such as maximum output voltages, to protect your physical hardware. Step 2: Build the Control Logic The Quarc library has a wide range of

. This library provides specialized blocks that extend standard Simulink functionality for real-time environments. HIL (Hardware-In-the-Loop):

These blocks allow non-periodic tasks to run asynchronously to the main control loop, which is essential for handling unpredictable data packets without interrupting high-speed control tasks. 3. Data Visualization (Advanced Plots)

– Interface with physical devices including Quanser haptic devices, robots, fieldbus terminals, and third-party peripherals. on various targets, including Windows and Linux, and

Build your feedback control loop (such as a PID or State-Space controller) using standard Simulink blocks.

Real-time performance can degrade if too many Simulink Scopes are open at once, as streaming graphical data to the host PC consumes bandwidth. Close unnecessary scopes during long testing runs.
