“…Some of these methods utilize electromotive fo rce (EMF), which is proportional to the motor speed. These methods estimate the EMF with a disturbance observer, an estimation of current error, and a model reference adaptive system [ 8 ] [9]. The pole position and rotor speed depends on the measurement and the direction of the EMF.…”

Various methods have been proposed to identify the flux position in an interior permanent magnet synchronous motor (IPMSM) without the use of mechanical sensors. To achieve this, a method that uses both the back electromotive force (EMF) and the saliency to identify the flux position in the IPMSM without the injection of high-frequency components at low speeds has been reported. We propose the extended method by controlling q-axis current derivative during zero voltage vector.

“…The latter are suitable only for the interior permanent magnet synchronous machine. Most of the model-based techniques detect the back-EMF vector, which holds information about the rotor position and speed, using either open-loop estimators [5], [6] or closed-loop estimators/observers [7], [8]. In some other model-based techniques rotor-flux vector is estimated directly [9].…”

This paper presents a sensorless control scheme for a permanent magnet synchronous generator (PMSG) in variable speed wind energy conversion system (WECS) applications. The rotor speed is estimated using recursive least square estimation (RLSE) algorithm using a simple equation which requires only the knowledge of rotor flux. A programmable low pass filter (PLPF) is implemented to obtain the rotor flux. The concept is analyzed in a wind speed sensorless variable speed direct drive PMSG WECS wherein the MPPT controller does not require the knowledge of wind speed, air density or mechanical parameter of the WECS. The machine side and grid side converters are vector controlled in rotor flux reference frame and grid voltage reference frame respectively. Results show good estimation accuracy.Index Terms-Permanent magnet synchronous generator, speed estimation, sensorless, vector control, wind energy conversion systems, maximum power point tracking control.

Efficient and precise sensorless speed control of Permanent Magnet Synchronous Motor (PMSM) requires accurate knowledge of rotor flux position and speed. In the present paper, an indirect rotor flux oriented scheme for sensorless speed control of PMSM is proposed in which the rotor flux position is estimated by direct integration of the estimated rotor speed to reduce the effect of system noise. The rotor flux magnitude and the rotor flux speed are estimated adaptively using stable Model Reference Adaptive System (MRAS) estimators. Simple stability analysis and design of the estimators are performed using linear control theory. The convergence of rotor position and speed estimation errors to zero is guaranteed. Simulation and experimental results obtained show excellent performance.
