Position and Speed Sensorless Control for IPMSM Based on Estimation of Position Error

A Sensorless Initial Rotor Position Estimation Scheme for a Vector Controlled IPMSM Drive

Vector field oriented control (VFOC) of permanent magnet synchronous motor (PMSM) drive requires accurate velocity information sensed by a speed or position sensor attached to the rotor. Nowadays, sensorless control is adopted in many industrial applications for reasons of robustness, cost, cabling and reliability. This paper presents a novel sensorless control strategy and initial rotor positi...

Sensorless Speed and Position Control of Induction Motor Drives

Controlled induction motor drives without mechanical speed sensors at the motor shaft have the attractions of low cost and high reliability. To replace the sensor, the information on the rotor speed is extracted from measured stator voltages and currents at the motor terminals. Vector controlled drives require estimating the magnitude and spatial orientation of the fundamental magnetic flux wav...

Position/speed Sensorless Control for Permanent-magnet Synchronous Machines

Position and Speed Sensorless Control of PMSM Drives Based on Adaptive Observer

This paper develops a model reference adaptive system (MRAS) based observer for sensorless vector control of permanent magnet synchronous motor (PMSM) drives. There are used two models in MRAS observer to estimate the linkage flux with relatively clean waveforms. The voltage model in stator reference is the reference model, and the current model in estimated rotor reference is the adaptive mode...

Sensorless Position Control of SPMLSM based on High-Gain Observer

The Network-on-Chip (NoC) approach is a promising solution to the increasing complexity of on-chip communication problems due to its high scalability. A NoC architecture design with ultra-low latency and high throughput is critical in order to support a wide range of applications. In this paper, we propose novel spatial-based NoC resource allocation algorithms to reduce the communication conges...
