Application Software Development - Motors Control

Job title

Engineer Application Software Development

Main aim of job (in brief no duties and responsibilities)

Development of application software for motors (DC, BLDC) like CFM, DTA, ETW in coordination with the global development teams in (various regions) following defined standards.

Application software comprises of:

• Customer interface software and user logic
• Commutation control logic
• diagnostic functions
• communication protocols (e.g. PWM, LIN, CAN)
• Calibration of ECU for software parameters

Specialized knowledge and skills

• Strong knowledge with the programming language C and Assembler
• Strong knowledge in programming of microcontrollers like Free scale S12X, Infineon TLE987x or similar
• Strong knowledge of embedded software development tools (compiler, debugger, emulator, etc.)
• Knowledge of electronics hardware/components and usage in application
• Good knowledge of software development life cycle, test and debugging methods
• Knowledge of software development for drives BLDC / Permanent Magnet Synchronous Motors (PMSM) motors will be an advantage
• Strong knowledge of communication protocols CAN/LIN and vector tools (CANoe, CANape, etc)
• Good written and verbal communication skill
• Working experience with Speed / Torque control algorithms for BLDC / PMSM e.g., Field Oriented Control (FOC),
• Direct Torque Control (DTC) etc.
• Working experience of Sensor-less Startup and Rotor Position Estimation algorithms e.g. Kalman Filter, Observer
• Working experience of 3-phase Current Measurement and reconstruction using Single Shunt method.
• Working experience of Modulation Techniques like Space Vector Pulse Width Modulation (SVPWM), Harmonic
• Injection, Field Weakening, Maximum Torque Per Ampere (MTPA) etc.
• Working experience of Control Systems Strategies e.g. P, PI, PID control
• Working experience of Fourier Transformation, Laplace Transformation, Transfer Functions etc.
• Expert in Functional Safety (ISO 26262) (Actual working experience not certification)
• Working experience with microcontrollers like NXP S12Z, Infineon TLE987x, S32K144 and Gate drivers like Infineon TLE9180, Texas Instrument DRV3256, DRV8363, UCC27712, UCC21530
