Allows developers to map joysticks, steering wheels, or keyboard inputs directly to control parameters in real time. The QUARC Workflow: From Model to Hardware
Use HIL Read and HIL Write to connect your controller to the virtual inputs/outputs.
While the code runs on the hardware, you can change gains, adjust setpoints, and view live signals directly on Simulink Scopes without stopping the controller. Key Benefits of Using QUARC Hard Real-Time Performance on Windows
To get the most out of the QUARC library in your next project, keep these best practices in mind: quarc library simulink
For engineers and researchers in control systems, robotics, and mechatronics, the leap from a mathematical model to a physical prototype is often fraught with challenges. Simulink, by The MathWorks, has long been the gold standard for model-based design, allowing users to simulate complex dynamic systems. However, the final step—deploying that controller to real hardware—typically requires tedious manual coding, driver integration, and real-time scheduling.
When you open the Simulink Library Browser after installing QUARC, you will find a dedicated QUARC Targets library. The blocks are organized into functional categories: 1. Hardware Integration (HIL Blocks)
Ensure your hardware and target PC can handle your chosen sampling frequency. Start at 1 kHz ( 0.001 s step size) and optimize from there. Allows developers to map joysticks, steering wheels, or
QuArc is a model-based design library for Simulink focused on control systems and embedded software development. It provides reusable blocks, templates, and verification/scalability features aimed at improving development speed, code quality, and traceability for embedded control applications.
The QUARC Targets Library expands standard Simulink capabilities with specialized blocks:
The QUARC Blockset is organized into several sub-libraries. Let’s break down the most important categories. Key Benefits of Using QUARC Hard Real-Time Performance
: The library includes specialized blocks for I/O, including Data Acquisition (DAQ) boards, cameras, and communication protocols (SPI, I2C, PWM).
For roboticists and computer vision engineers, QUARC simplifies complex sensor integration.
QUARC operates on a , where the user designs controllers in the Simulink Development Environment (SDE) on a host PC and deploys them to a local or remote real-time target.
To use QUARC within Simulink, it must be properly initialized in the MATLAB environment: Automatic Setup
