: QUARC's advanced blocks enable sophisticated research. For systems like the Quanser Magnetic Levitation (QMagLev) system, researchers can leverage QUARC for real-time parameter tuning, data logging, and implementing advanced algorithms such as state observers and nonlinear control. The Continuous library's Extended Kalman Filter and Nonlinear State-Space blocks, and the Communications blockset for inter-process communication, are ideal for rapid prototyping of complex state estimators and multi-agent systems.
Transmits raw data, matrices, or structured packets across networks with minimal overhead, crucial for distributed control systems. Multimedia & Advanced Interfacing
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.
QUARC serves as this bridge. It compiles Simulink models into executable code that runs on a target operating system (such as Windows, Linux, or QNX) with hard real-time performance. This means your control loops execute with deterministic timing, preventing hazardous jitter in physical hardware systems. Core Components of the QUARC Library quarc library simulink
QUARC is a powerful real-time control software developed by Quanser. It integrates seamlessly with MathWorks Simulink to turn a standard computer into a real-time control workstation.
The library offers unique functionality, such as the Asynchronous Thread block , allowing you to create non-periodic tasks that run independently of the main controller loop. This is essential for: Data logging Network communications 4. Advanced Visualization and Data Logging
Ensure QUARC is installed and integrated with MATLAB/Simulink. : QUARC's advanced blocks enable sophisticated research
Create your control algorithm using standard Simulink blocks and QUARC HIL blocks for input/output.
QUARC, on the other hand, offers a completely integrated workflow:
Configure complex peripherals (like SPI, I2C, PWM, and DAQ cards) using standard Simulink blocks. Transmits raw data, matrices, or structured packets across
to define protocols, making it easy to switch communication methods by simply updating a string. Asynchronous Thread Blocks
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:
Typically, the is installed after MATLAB/Simulink. If a model is opened and displays errors about missing blocks ("'QUARC Targets' not installed" or "quarc_library"), it often indicates an installation issue.
