: This is one of QUARC's most powerful advanced features. It allows supervisory models to be created that can download, load, and switch between multiple different models on a target system while it is running , all under the control of a Simulink diagram. This is essential for applications requiring mission reconfiguration or fail-safe mode switching.
QUARC allows Simulink models to run at deterministic rates on various target operating systems, such as Windows or Linux (RT-Preempt). This ensures that your control loops are never interrupted by background OS tasks. 🟢 Hardware-in-the-Loop (HIL)
: Used to ensure the model runs at a precise hardware clock rate. 4. Build and Run Once your model is assembled: quarc library simulink
: These allow you to interface with data acquisition (DAQ) cards. A key feature is the ability to swap out the physical hardware for a model by changing a single parameter in the block. Communications Blockset
QUARC's support for sets it apart from many other real-time solutions. This capability allows one running QUARC model to be dynamically replaced with another within a single sampling interval. A supervisory model can monitor system states and trigger a seamless switch between controllers for different operational modes (e.g., "swing-up" vs. "balancing" for an inverted pendulum). Crucially, blocks are provided for transferring state data between the switched-out and switched-in models, ensuring continuity and stability during the transition. This is a powerful tool for applications requiring mission reconfiguration, such as autonomous vehicles switching between automatic control and a manual emergency override. : This is one of QUARC's most powerful advanced features
Quarc is a real-time control and data acquisition software environment that integrates tightly with MATLAB/Simulink to deploy algorithms onto hardware targets (notably Quanser and other real-time platforms). The Quarc library for Simulink provides blocks and interfaces that simplify model-based design, real-time I/O, and rapid prototyping of control systems.
What or Quanser plant are you trying to interface with? What version of MATLAB/Simulink are you running? QUARC allows Simulink models to run at deterministic
The , developed by Quanser, bridges this gap. It turns MATLAB and Simulink into a powerful, real-time rapid control prototyping (RCP) and hardware-in-the-loop (HIL) testing environment. What is the QUARC Library?
By following this article, you should now have a good understanding of the Quarc library and its applications in control systems development using Simulink. Whether you're a seasoned developer or just starting out, the Quarc library is definitely worth considering for your next project.
: This set of source blocks goes beyond Simulink's standard offerings. It includes blocks for generating sigmoid trajectories, measuring real-time execution time, outputting the current date and time, and even reading data from a file on the local system.
– This component runs in the real-time environment (on the target system) and manages the real-time code. Unlike WinCon Client, which required a desktop operating system, the QUARC Target Manager is designed for embedded systems and runs directly on the target, making it far more suitable for deployment scenarios.
