Quarc is a high-performance add-on for Simulink that transforms it from a design tool into a rapid control prototyping environment. It allows engineers to run Simulink models directly on real-time hardware without writing low-level C code.
You can now use standard Simulink Scopes to view hardware data in real time and modify gains on the fly while the physical system is running. Best Practices for QUARC Development
Beyond standard Simulink scopes, QUARC provides improved tools like the , which outperforms standard Simulink graphs, allowing for complex plotting of multiple curves simultaneously. How to Get Started with QUARC in Simulink Using QUARC involves a straightforward workflow:
Stream signals from the hardware target back to Simulink Scopes and MATLAB workspaces instantly. quarc library simulink
I can provide more specific guidance on your project. Let me know:
Under , select a fixed-step solver (e.g., ode4 or ode1 ) and set an appropriate fundamental sample time (typically 0.001 seconds for a 1 kHz loop). Step 2: Adding QUARC Infrastructure
: A protocol-independent communication framework supporting TCP/IP, UDP, serial, shared memory, and SPI. Quarc is a high-performance add-on for Simulink that

Requires careful setup (kernel patches on Linux, disabling power management, etc.). Not as plug-and-play as advertised for some systems.
Create your control algorithm using standard Simulink blocks and QUARC HIL blocks for input/output. Let me know: Under , select a fixed-step solver (e
QUARC blocks drag-and-drop into Simulink like native blocks. No separate coding environment—just add I/O blocks, set sample time, and hit "Run" to execute in real time.
: You can develop a model on your host PC and deploy it to a remote target (like a Quanser Qube or a Raspberry Pi) via a single click using the "Monitor and Tune" feature.
Run models on Windows targets, specialized Quanser QPid/Q-Control boards, or embedded Linux devices like the Raspberry Pi. Core Blocks in the QUARC Library
Replace your simulated plant model with QUARC HIL blocks connected to your actual physical system.
