“…For the position sensorless control of the PM Synchronous Machine, observer algorithm is designed using sliding mode controller, therefore, it is named as SMO also. The drawbacks of conventional SMO such as chattering phenomena & slight delay in the estimation of the rotor position are reported in [19][20][21][22][23][24][25][26][27].…”

Abstract: Permanent magnet synchronous motors (PMSM) are gaining popularity day by day and will rule in the next decade as these motors have several benefits over induction motor such more efficiency, low noise operation, reduced size, and maintenance free operation. These motors require a position sensor for its control, which makes it costlier, increase the size and low reliability. The development of fast microcontroller, IGBT devices, and high density permanent materials has opened the gate of industrial and commercial market for PM Synchronous Machine. The researchers from various corners of the world are working hard from more than two decades to evolve the sensorless control scheme for rotor flux estimation. A sensorless control schemes proposed till date works satisfactory, but, high performance is still a challenge. The paper presents a review of most popular robust SMO technique for position sensorless control of PM-Synchronous Motor with its benefits & drawbacks.

“…This enables the elimination of a differentiation process, which is important due to avoiding a numerical noise effect. The approach presented in [26] deals with the sensorless determination of the angle of rotation and studies the control of the PMSM machine using a phase-locked loop (PLL). The presented methods enable a discrete form of control with a low number of signal samples per voltage period to be used.…”

The article presents an innovative construction of the Axial Flux Permanent Magnet (AFPM) machine designed for generator performance, which provides the shape of induced voltage that enables estimation of the speed and rotational angle of the machine rotor. Design solutions were proposed, the aim of which is to limit energy losses as a result of the occurrence of eddy currents. The method of direct estimation of the value of the rotational speed and rotational angle of the machine rotor was proposed and investigated on the basis of the measurements of induced voltages and machine phase currents. The advantage of the machine is the utilization of simple and easy-to-use computational procedures. The acquired results were compared with the results obtained for estimation performed by using the Unscented Kalman Filter (UKF).

“…In this case, the rotor position and speed should be estimated accurately. Unfortunately, most of sensorless estimation techniques cannot work well at standstill and low speed due to low back-EMF [6].…”

The sensorless control method for the high speed permanent magnet synchronous machine without position and speed sensor in the start process of a 30kW microturbine generation system is investigated in this paper. The open-loop speed control mode based on current control is applied at low speed, and the closed-loop sensorless vector control mode is used at medium and high speed. The rotor position and speed estimation algorithm is implemented using an open-loop observer based on back-EMF in the vector control. On the basis of detailed description of the proposed start-up strategy, the simulation and experimental system has been built. Several critical issues were analyzed, including the setting method of the reference speed profile in open-loop mode and the transition time selection from open-loop mode to closed vector control. The simulation and experimental results demonstrate the proposed sensorless control method can meet the requirements of the start process for microtubine generation system, and possesses high static and dynamic performance at large-scale speed.Index Terms -microturbine generation system, high speed permanent magnet machine, sensorless, vector control
