Quarc Library Simulink

Bridging the Gap Between Simulation and Real-Time Hardware

In the world of control systems and robotics, the transition from a Simulink simulation to a working physical prototype is often fraught with complexity. This is where the Quarc Library (by Quanser) becomes an indispensable tool.

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.

Below is a breakdown of the key features that make the Quarc Library a standard in academic and industrial research.

Quarc’s library blocks act as a universal translator between your logic and the physical hardware.

Quarc is hardware-agnostic to a degree, though it is heavily optimized for Quanser hardware environments.

The Quarc library for Simulink streamlines converting Simulink control designs into real-time hardware implementations by providing hardware-specific I/O blocks, real-time orchestration, and deployment tools. Following fixed-step design, hardware abstraction, and incremental testing ensures reliable, deterministic control on supported targets.

QUARC Targets Library is a specialized extension for Simulink that enables high-performance, real-time code generation and hardware-in-the-loop (HIL) testing. Unlike standard Simulink libraries, it provides unique blocks for hardware access, asynchronous communications, and advanced visualization. Core Capabilities Hardware Interfacing HIL (Hardware-in-the-Loop)

blocks allow for direct access to data acquisition cards. Users can switch hardware targets for an entire model by modifying a single parameter. Real-Time Performance : It supports hard real-time execution

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

enable non-periodic tasks (e.g., event-driven code or idle worker threads) to run independently of the model's main sample rate. Advanced Sinks : QUARC includes specialized plotting blocks like Time Figure

that offer superior performance and can be integrated into custom MATLAB GUIs. Installation & Configuration

To use QUARC within Simulink, it must be properly initialized in the MATLAB environment: Automatic Setup

: If MATLAB is installed before QUARC, it is typically configured automatically. Manual Setup

: If needed, run the following command in the MATLAB Command Window to add QUARC to the path: quarc_setup Use code with caution. Copied to clipboard Opening the Library : You can access the blockset via the Simulink Library Browser or by entering qc_open_library('quarc_library') in the command window.

(Quanser Real-Time Control) is a rapid control prototyping platform that integrates with

to enable the design, development, and deployment of real-time applications directly onto hardware. It serves as a bridge between high-level graphical modeling and real-world execution, allowing users to run controllers on various targets—such as Windows or Linux—without writing manual code. The QUARC Targets Library The core of QUARC’s functionality within Simulink is the QUARC Targets Library

. This library provides specialized blocks that extend standard Simulink capabilities for hardware-in-the-loop (HIL) testing and real-time communication. Data Acquisition (DAQ):

Blocks that allow direct interaction with hardware sensors and actuators. The Immediate I/O

blocks, for instance, read or write to channels every time the block executes, which is critical for time-sensitive control loops. Communications:

A protocol-independent framework that uses Universal Resource Identifiers (URIs) to define connections. It supports various protocols like TCP/IP, UDP, serial, SPI, and I2C. Asynchronous Threads:

These blocks enable the creation of non-periodic threads for tasks like event-driven code or background communications, which run independently of the main model sample rate. Continuous Blocks: Bridging the Gap Between Simulation and Real-Time Hardware

Includes advanced tools for nonlinear state-space systems and extended Kalman filters. Key Features and Capabilities
