3. FACULTY ADVISOR DR. G. MARSHALL MOLEN, P.E. Education: ● Ph.D., Electrical Engineering, Texas Tech University, 1974 ● M.S., Electrical Engineering, Texas Tech University, 1969 ● B.S., Electrical Engineering, Texas Tech University, 1968 Research: ● Pulsed Power ● High Voltage ● High Energy Lasers

4. OVERVIEW ● Problem ● Solution ● Practical Constraints ● Testing of Technical Constraints ● Timeline ● Progress ● Conclusion

5. PROBLEM ● Interest in UAVs is on the rise. ● Companies are looking to incorporate UAVs in their current solutions. ● Researching possible solutions is a time consuming process.

6. SOLUTION ● Our product will provide a basis for UAVs that will allow for the addition of multiple subsystems. ● This can help companies jumpstart the design process.

7. SYSTEM OVERVIEW MOTOR DRIVE MOTORMICROCONTROLLER CAN BUS HOST PC

8. PRACTICAL CONSTRAINTS Safety Health

9. SAFETY ● Selection of load. ● Motor should be able to handle the load. ● Risk of injury to self or fellow workers with certain loads. https://www.flickr.com/photos/diabloazul/5608946195

10. HEALTH ● High current can be dangerous or fatal. ● This system can draw up to 3A. ● Care must be taken to avoid electrical shock. https://ownersrepny.files.wordpress.com/2011/07/electric_shock.jpg

11. TESTING OF TECHNICAL CONSTRAINTS COMMUNICATIONCAN BUS CONNECTS SUBSYSTEMS SAMPLE RATEMUST TAKE DATA SAMPLES AT A MINIMUM RATE OF 100 SAMPLES/S OPERATING VOLTAGEOPERATES WITHIN 18V - 26V SPEED CONTROLCONSTANT ROTATIONAL SPEEDS FAULT DETECTIONIDENTIFY AND RESPOND TO SYSTEM ERRORS

12. COMMUNICATION : CAN BUS CAN analyzer (Kvaser) used to listen to the CAN bus BOOT UP MSG NMT MSG ENABLE DRIVE VELOCITY MODE SET: 100 RPM SET 200 RPM SET 300 RPM SET 100 RPM SET 0 RPM DISABLE

14. OPERATING VOLTAGE ● Operates between 18V to 26V. ● Voltage divider with predefined voltage levels. ● System voltage measured using ADC. ● Throws flag when voltage is above 26V and below 18V.

15. SPEED CONTROL ● Set RPM. ● Check RPM. ● Adjust Values. Drive reset Drive Response NMT ENABLE DRIVE SYNC MSG Response PDO MODE: Velocity SET VELOCITY: 400RPM SYNC MSG Response PDO HOST PC: Set 800 RPM SYNC MSG Response PDO SET VELOCITY: 800 RPM SYNC MSG Response PDO

16. FAULT DETECTION ● Voltage ○ Overvoltage and Under- voltage error handling. ● Current ○ Insufficient Current Error if task requires more current than current available. ● Unable to Connect ○ Cannot communicate with motor drive.

17. INSUFFICIENT CURRENT Set Current and VoltageMonitored Current and Voltage Bridge being disabled after an inability to draw current for the specific task.

18. RESET DRIVE ERROR:No response from drive Host requests reset (03) Clear error RESET DRIVE ERROR: no response MANUAL DRIVE POWER UP Host requests reset (03) Clear error RESET DRIVE BOOT UP MSG UNABLE TO CONNECT
