: This category provides blocks for interfacing with specific physical hardware, including Quanser's haptic devices, robots, and fieldbus terminals like EtherCAT.
QUARC includes a robust communication stack that bypasses standard TCP/IP latency limitations.
– Simulink acts as the comprehensive front-end for generating real-time code, tuning parameters, and visualizing data. Unlike WinCon, where plotting required a separate application (WinCon Server), QUARC allows Simulink sink blocks—including Scopes and Displays—to work directly with the real-time code.
QUARC downloads the binary to the target machine and runs it at a precise, deterministic sample rate (often up to 1 kHz or higher). quarc library simulink
The platform also supports fieldbus technologies such as EtherCAT, multimedia devices including Kinect sensors, and specialized robotics platforms like the QBot 2 autonomous ground robot. The QBot 2, for example, integrates QUARC with MATLAB and Simulink to enable users to develop controllers on a host computer and cross-compile them for the embedded Gumstix target on the robot.
– Starting with QUARC 2.0, the platform includes tools for creating and animating 3D visualizations of simulations or real-time code, with support for multiple 3D viewer client connections and plugins for Autodesk’s 3ds Max and Blender 3D.
: These blocks offer advanced continuous-time functionality beyond Simulink’s native set. Key blocks include the Nonlinear State-Space block for implementing custom ODEs like x_dot = f(x,u) , an Extended Kalman Filter for state estimation in nonlinear systems, and a Controller block that can implement three commonly used controllers simultaneously. : This category provides blocks for interfacing with
– Perhaps one of the most innovative aspects, these blocks allow devices connected to the host PC—such as game controllers, keyboards, mice, and even Nintendo Wii Remotes—to control real-time code running on local or remote targets. For instance, a Host Game Controller block can be used to tune PID parameters on a mobile robot in real-time.
Turn Simulink models into runnable controllers instantly.
QUARCTM is the most efficient way to design, develop, deploy and validate real-time applications on hardware using Simulink®. QUARC Targets Library - Unleashing the Power of QUARC The QBot 2, for example, integrates QUARC with
: You can quickly open specific sub-libraries by typing commands like qc_open_library('quarc_library/Sinks') in the MATLAB Command Window. 3. Essential Hardware Blocks
Test physical controllers against virtual plants or vice versa.
By bridging the gap between mathematical models and physical hardware, QUARC allows engineers and researchers to target, execute, and modify code on external hardware platforms without leaving the Simulink environment. 1. What is the QUARC Library in Simulink?
