PROFESSIONAL EXPERIENCE:

Confidential, Tucson, AZ

Responsibilities:

• BLDC motor control software design and implementation for 300W rotary and 3kW linear custom-designed electric motor actuators with 48V and 375V power buses. Position, velocity, and current/back-EMF controls run at a 15 kHz inner loop rate. Participated in customer demonstrations and performance/environmental testing.
• Atmel SoC interfaces with a resolver chip F2D converter for determining the motor rotational position, a delta/sigma sinc3 filter chip for determining the motor phase currents, and IGBT and Power MOSFET H-bridge circuits driven with PWM signals with dead time to produce the motor phase currents. Assisted with hardware design. Also ported the code to a faster SoC, gaining floating point capability and higher resolution PWM signals.
• In “C” using Atmel SAM9XE512, IAR Embedded Workbench, and WinMerge differences tool. No RTOS or software libraries used. Three communications channels, scaled integer math, fault detection and reset, and memory dumper snapshot tool using J-Link and Excel for debugging and data anaysis.
