Sensorless Field Oriented Control of PMSM Motors
Designers can expect environmental demands to continue to drive the need for advanced motor control techniques that produce energy efficient air conditioners, washing machines, and other home appliances. The implementation of advanced, cost-effective motor control algorithms is now a reality thanks to the new generation of Digital Signal Controllers (DSCs). Field Oriented Control (FOC) has emerged as the leading method to achieve environmental demands driven by . This application note discusses implementation of a sensorless Field Oriented Control (FOC) algorithm for Permanent Magnet Synchronous Motors (PMSMs) using the Microchip dsPIC DSC family.
