Quarc Library Simulink May 2026

The QUARC Basic Communications library for Simulink provides a high-level abstraction for data streaming and hardware interfacing. Whether you are building an autonomous drone, a haptic interface, or a complex industrial controller, QUARC simplifies the process of getting Simulink models to talk to the real world. What is the QUARC Library in Simulink?

adds specialized blocksets that allow these models to interact directly with hardware in real-time. Core Components of the QUARC Library quarc library simulink

Example Minimal Model Structure (conceptual)

  • Source: Reference signal block
  • Controller: PID or state-space controller
  • Actuator interface: Quarc analog out / PWM block
  • Sensor interface: Quarc encoder / analog in block
  • Monitoring: Quarc scope or External Mode blocks
  • Init/Term: Quarc initialization and shutdown blocks

Key features:

  • Real-time synchronization – Simulink blocks execute deterministically with specified sample times.
  • Device drivers – Pre-built blocks for sensors (encoders, accelerometers) and actuators (motors, servos).
  • Communication – Supports PCIe, USB, Ethernet, and Wi-Fi connections to Quanser I/O boards and embedded targets (e.g., QPIDe, Q8-USB).
  • Monitoring & logging – Stream data to Simulink scopes, or log to MATLAB workspace for analysis.
