Reads analog signals (sensors), digital lines, and encoder counts; writes control signals to motors or actuators. quarc library simulink
: Select the QUARC target (e.g., quarc_win64 ) in the Model Configuration Parameters.
The HIL Initialize block cannot establish communication with the hardware. Solution: Verify physical USB/PCI connections and ensure the correct Quanser hardware drivers are installed via the device manager. Used to read analog/digital inputs (like encoder positions
– The classic inverted pendulum problem serves as an excellent demonstration of QUARC’s capabilities. Using the QUBE-Servo 2 rotary inverted pendulum, for example, students can design balancing controllers, implement swing-up strategies, and even explore reinforcement learning-based control—all through the same Simulink/QUARC workflow.
When you install QUARC, a dedicated section is added to your Simulink Library Browser. The blocks are categorized by function to streamline model architecture. Hardware-in-the-Loop (HIL) API Blocks The HIL Initialize block cannot establish communication with
Beyond simple input-output loops, QUARC scales effectively to handle complex, enterprise-level applications. Asynchronous Threading

Your Simulink scopes will now display real-time physical data, and modifying a slider gain in Simulink will instantly change the behavior of the real-world hardware. 4. Advanced Capabilities: Multi-Tasking and Streaming
– Quanser lab workstations, integrated with QUARC, enable interactive project-based learning in control systems, mechatronics, and robotics curricula. Students can design controllers in Simulink, test them in simulation, then deploy them to physical hardware—gaining hands-on experience with rapid control prototyping. Laboratory exercises cover topics from basic PID control to advanced concepts like inverted pendulum balancing, active suspension systems, and multi-agent collaborative control.
