S32K344 - FOC with dual single current measurement

These examples demonstrate a 3-phase Permanent Magnet Synchronous Motor (PMSM) vector control (Field Oriented Control - FOC) drive with 1- shunt current sensing with and without position sensor. This design serves as an example of motor control design using NXP S32K3 automotive family.

Examples were designed on S32K344 Brushless Direct Current and Permanent Magnet Synchronous Motor Control Development Kit. 

C-project based examples are part of MCSPTE1AK344 Development Kit Application Software. An innovative drivers set, Real-Time Drivers (RTD),are used to configure and control the MCU. It complies with Automotive-SPICE, ISO 26262, ISO 9001 and IATF 16949. Production-ready Automotive Math and Motor Control Library set provides essential building blocks for algorithm. FreeMASTER is used as useful run-time debugging tool.

Application software contains: 

• MCSPTE1AK344_PMSM_FOC_1Sh_ll - Low-level drivers of RTD and S32 Design Studio Configuration Tools (S32CT) are used to demonstrate non-AUTOSAR approach. Since the structure of the example is similar to dual shunt example, detailed description of the example can be found in application note AN13767 and MCSPTE1AK344 - single shunt addendum.pdf (which highlights changes for single shunt)  attached to this article .
• MCSPTE1AK344_PMSM_FOC_1Sh_as_tr - RTD, EB (Elektrobit) tresos Studio and S32 Design Studio are used to demonstrate AUTOSAR (AUTomotive Open System ARchitecture) approach. Since the structure of the example is similar to dual shunt example, detailed description of the example can be found in application note AN13884 and MCSPTE1AK344 - single shunt addendum.pdf (which highlights changes for single shunt)  attached to this article .

MATLAB Simulink based project (Motor Control PMSM Single Shunt Example - s32k344_mc_pmsm_1sh_ebt) is build using Model-Based Design Toolbox (MBDT) and can be downloaded from NXP Model-Based Design Toolbox for S32K3xx - version 1.4.0 or newer releases.
