This reference design is a 750W motor drive for a washing machine or similar equipment, which illustrates a method to implement sensorless field oriented control (FOC) for a three-phase permanent magnet synchronous motor (PMSM) with a flux, angle, speed and torque observer (FAST) software encoder or enhanced sliding-mode observer (eSMO). With a modular design, this reference design supports both the C2000™ microcontroller (MCU) and MSPM0 MCU daughterboard on the same motherboard. The hardware and software available with this reference design are tested and ready-to-use to help accelerate development time to market. The hardware design details and test results are found in the design guide.
The MathWorks model-based approach enables faster development, requires fewer engineering resources, and needs no software expertise. It decouples control algorithm development from firmware development and is portable across C2000 microcontroller product families. The simulation capability enables offline development, tuning and validation of control algorithms.
MathWorks MATLAB & Simulink example models are included in the MotorControl SDK for C2000™ uses:
