QuArc Library for Simulink — Detailed Review

Workflow Summary: How It Works

1. Design: Create a control algorithm using Simulink blocks and the Quarc library (e.g., HIL Initialize, HIL Read Encoder, HIL Write Analog).
2. Simulate: Verify the logic using standard Simulink simulation tools.
3. Build: Click the "Build" button. Quarc automatically generates C code (via the Real-Time Workshop), cross-compiles it, and downloads it to the target hardware or prepares it to run on the local Windows machine.
4. Run & Tune: Start the model. Use the Soft Scope to monitor signals and change gains in real-time to tune the physical response.

Part 1: What is the QUARC Library?

Part 4: A Practical Step-by-Step Workflow

Let’s walk through a typical workflow of using QUARC Library for Simulink.

3.2. Hardware I/O Drivers

This is the most utilized section of the library. Quarc provides pre-written drivers for a vast array of hardware data acquisition (DAQ) cards and sensors. This includes:

• Data Acquisition: Interface blocks for Quanser DAQ cards (e.g., Q2-USB, Q8-USB) and third-party cards (e.g., National Instruments).
• Robotics: Specific blocks for mobile robots (QBot 2/3/4) and manipulators (e.g., PUMA, LYNX).
• Sensors and Actuators: Blocks for encoders, analog outputs (DAC), digital inputs/outputs, and PWM generation.

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
