Position/speed Sensorless Control for Permanent-magnet Synchronous Machines

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...

Accurate Rotor Position Detection and Sensorless Control of SRM for Super-High Speed Operation

Based on the general nonlinear magnetizing model (GNMM) from our previous research work, an improved method of detecting rotor position for sensorless control of SRMs in super-high speed operation has been developed. With minimum input data, the approximated GNMM is obtained and the rotor speed estimated. Then the rotor position is detected by the motion equation. To remove rotor position error...

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...
