  1. BLDC Motor control using FPGA and LABVIEW Author: Gabriel ZSURZSAN Scientific supervisor: Prof. dr. eng. Aurel GONTEAN

  2. Motivation • Motors – a basic component of our lives • FPGA – challenging but extremely flexible • LabVIEW– powerful and intuitive development platform • Wii Remote – adds a much-needed fun factor and freedom of control to the project Gabriel ZSURZSAN

  3. The Hardware Platform • Nintendo Wii Remote • Hurst BLDC motor • Motor Driver (partial schematic) • Spartan 3E Starter Kit Gabriel ZSURZSAN

  4. The Software Platform • LabVIEW 2009 provides a comprehensive development environment allowing access to all the resources necessary in order to implement the present project, either in its standard form or through one of its modules • FPGA Module • PID Module Gabriel ZSURZSAN

  5. The Software Platform • LabVIEW greatly shortens development time Gabriel ZSURZSAN

  6. Full project chain • The WiiMote communicates with the laptop through Bluetooth • LabVIEW uses a .NET framework DLL in order to initialize the remote and interpret the data received Gabriel ZSURZSAN

  7. Full project chain • LabVIEW FPGA module manages the programming of the FPGA, as well as communication between the host and target VIs through USB Gabriel ZSURZSAN

  8. Full project chain • The FPGA generates a PWM signal to drive the motor • The Hall signals generated on the BLDC side are read by the FPGA, determining correct energizing of driver transistors and motor speed for PID loop adjustments • PID feedback loop is implemented on the FPGA Driver Gabriel ZSURZSAN

  9. Interface • Straightforward • Intuitive • Easy to use Gabriel ZSURZSAN

  10. Some results Gabriel ZSURZSAN

  11. Observations & Conclusions • Hall sensors are really noisy • WiiMote accelerometer is very sensitive • PID loop manual tuning is difficult and may take long • WiiMote control is very intuitive, extra visual feedback added by the implemented 3D model • LabVIEW allows for easily interpretable results • PID response follows the setpoint accurately, giving no overshoot but a 10% undershoot Gabriel ZSURZSAN

  12. My personal remark: It was FUN! Gabriel ZSURZSAN
