Two-DOF XY Linear Motor Platform Construction

Overview

This project presents a two-degree-of-freedom XY motion platform where both X and Y axes are driven by linear motors. Magnetic scales provide precise displacement measurement, limit switches ensure motion safety, and accelerometers on each axis collect dynamic information. The system is controlled via Simulink on a host PC combined with a DAQ device for closed-loop control and data acquisition, supporting motion control experiments, algorithm validation, and dynamic analysis. ---

System Architecture

Signal flow summary: 1. Simulink controller generates motion control commands → motor drivers. 2. Drivers actuate X-axis and Y-axis linear motors to execute motion. 3. Magnetic scales measure X/Y axis displacement. 4. Accelerometers measure X/Y axis acceleration. 5. Limit switches monitor X/Y axis extreme positions. 6. All sensor data and limit switch states feed back to the Simulink controller.

Experimental Setup

Hardware Configuration

Platform Compatibility Note

This system was validated under QUARC / Simulink. The signal interfaces (analog voltage, encoder, digital I/O) are electrically compatible with real-time control platforms including dSPACE, Speedgoat, and NI systems.

Applicable Scenarios

• Graduate research: multi-axis linear motor motion control thesis experiments
• Precision automation: XY stage construction and contouring control
• HIL simulation: closed-loop motion control with dual-axis feedback
• Control course labs: visualizable and reproducible 2-DOF motion control platform
