Design of a System-on-Chip PMSM Drive Sensorless Control

The Sliding-Mode Position and Speed Observer is a simple and well-known mechanical sensor-less solution for Permanent Magnet Synchronous Motors (PMSMs) that is inherently robust in the medium-high speed range. The paper proposes a Field Programmable Gate Array (FPGA) implementation of a simple observer exploiting the high computational power of the device aiming to improve the speed estimation behavior and to make a step towards a System on Programmable Chip (SOPC) sensor-less PMSM drive.
