Title: 

Motor Control Engineer

Summary:

• Developing motor control algorithms, calibrations, and modeling in mechanical system;
• Developing mechanical test plans and processing electro-mechanical system testing data from the lab experiments. 

Duties and responsibilities: 

1. Develop and validate advanced motor control algorithms and control strategy for electro-mechanical system both in the laboratory and in vehicle level.
2. Develop state-feedback field-oriented controls (FOC) and robust state observers
3. Develop over-modulation algorithm using state-of-art techniques
4. Optimize machine mechanical (position/speed) sensor configuration and design advanced speed controller to attenuate system mechanical torque oscillation induced in vehicle dynamics.
5. Perform parameter calibration using back-to-back motor dyno and full-scale drivetrain dyno.
6. Perform vehicle level testing to obtain smooth communication between VCU (vehicle control unit), electrical motor and internal combustion engine.
7. Post-process experimental data using LabVIEW/Matlab for control algorithm development.
8. Define specification of hardware components including torque transducer, power analyzer, temperature sensors, position, voltage, and current sensors.
9. Design and implement motor control algorithm development with hardware-in-the-loop (HIL) and software-in-the-loop (SIL) simulations.

Required Education and Experience:

• MS degree in Electrical/Mechanical Engineering + 6 months experience in motor control. Or PhD degree in Electrical/Mechanical Engineering.
• Having used engineering tools such Vector PREEvision or similar to create network or communication designs and to understanding wiring schematics
• Experience with failure analysis methodology like FMEA and fault trees
• Experience with standard EE lab instruments (oscilloscope, multimeters, data bus analysis tools..)
• Motivation to make complicated systems work together
• Electric vehicle systems and hands-on integration testing experience
• Creativity in your design
• Motivation to make a difference in the automotive industry
• Ability to build stuff with your hands
• Great communication skills
