   Analysis of a Position Sensorless Control of a Salient-Pole Synchronous Reluctance Machine from Standstill to High-Speed Range
By Mario NIKOWITZ [View]
[Download]

Abstract: This paper discusses the position sensorless control of a salient-pole synchronous-reluctance machine (SynRM) whose performance is analysed. Depending on the rotational speed of the machine different methods have to be applied. At low-speed range the INFORM method is used, which is based on the magnetic anisotropy of the rotor. At high-speed range two different methods are implemented and compared. The first method is the Back-EMF model, which is based on the flux estimation by integrating the induced voltage. The second method, the short-circuit method, directly uses the measured electrical quantities to calculate the rotor position. No further integration or other dynamical operations are necessary, which increases the dynamic of the position sensorless control model. These mentioned position sensorless control methods were implemented and tested on a prototype to verify the performance of each algorithm.

   Classification and review of MTPA algorithms for synchronous reluctance and interior permanent magnet motor drives
By Fabio TINAZZI [View]
[Download]

Abstract: The MTPA algorithms are attractive solutions for reaching very high energy efficient drives. The paper presents a general formulation of the MTPA problem statement, including also the magnetic saturation in the formulation. A classification and a review of the MTPA techniques is proposed in this paper. A distinctive feature of the proposed classification is the highlighting of the most important characteristics (e.g. needs of motor parameters, signal injection, self-commissioning tests, etc.) of each technique. Also, offline and online techniques are thoroughly discussed. All synchronous motors, with or without permanent magnets, are considered.

   Interpretation of Measured IPMSM Flux Tables for Parameter Identification
By Felix BERTELE [View]
[Download]

Abstract: A widespread open loop torque control method for an interior permanent magnet synchronous machine (IPMSM) is using look up tables created from a flux measurement ([1], [2], [3]).To generate the calibration data a characterisation measurement is usually performed. This contribution describes methods to identify misalignment effects and evaluate the measurement data. The identified misalignment is used to correct the measurement result and to improve the calibration data. This improvement is necessary to reach the high requirements for torque accuracy, voltage usage and controller stability for an IPMSM, e.g. in hybrid drive systems. Furthermore precise calibration data can improve effectiveness of functions observing internal physical effects such as sensor less control or temperature observers.

   Wavelet Filtering Based Position Estimation of Sensorless Interior Permanent Magnet Synchronous Motor Drives
By Gaolin WANG [View]
[Download]

Abstract: Filtering method exerts direct effects on extracting high frequency current signal in carrier injection based sensorless control for IPMSM drives, and further affects the position estimation accuracy. A wavelet based filtering approach superior to conventional Butterworth band-pass filter is proposed and verified on a 2.2-kW IPMSM sensorless drives.
