Hardware prototyping of an intelligent current dq PI controller for FOC PMSM drive

Field Oriented Control (FOC) Permanent Magnet Synchronous Motor (PMSM) is a commutator less servo drive which provides high controllability, greater efficiency, superior torque to inertia ratio and high power density. However, the performance of FOC-PMSM depends on the driver circuits, which requires expensive computing elements. Besides, an intelligent current regulator is desired for a highly precise driver. This research proposed a hardwire prototype of current dq PI controller as a part of real-time hardwired motion intelligent driver which was previously solved using software and firmware dependent modules. The outcome will be a single chip current dq PI controller for FOC-PMSM drive.
