This paper proposes fast initial position estimation of IPMSMs (interior permanent magnet synchronous motors) that is based on intentional pulse voltage injection and comb filters. Most initial position estimation methods utilize the amplitude or differential values of high-frequency currents, and the performance of sensorless control depends on the algorithm to reconstruct these values. Although Fourier series expansion, which requires some low-pass filters (LPFs), is utilized generally, the filters degrade the response of position estimation. This paper focuses on the algorithm for initial position estimation of IPMSMs at standstill, and proposes a new algorithm using comb filters that can rapidly calculate the amplitude values of high-frequency currents and improve the initial position estimation performance. In addition, this paper experimentally shows the performance of the initial position estimation, starting characteristics of sensorless control, and characteristics of sensorless control including standstill under the load.

“…One of the typical examples is lift application, where the torque control at zero speed to prevent roll back and shock at the starting of the cage of the lift is prerequisite. And in other applications where higher starting torque and less acceleration time are key requirements, namely oil injected screw compressor and injection molding machine, the sensorless drives increase reliability and reduce cost (42) .…”

This paper presents the history of techniques used for sensorless control of the Interior Permanent Magnet Synchronous Machine (IPMSM) over the last 20 years. The techniques used in the first stage were based on the equivalent circuit of the IPMSM. They extracted rotor position information from the back EMF estimated through simple arithmetic. In the last 10 years, model reference adaptive control or observer-based control techniques have evolved and they have been used for the sensorless control of the IPMSM; however, the rotor position continues to be obtained from the back EMF. Simultaneously, sensorless control based on the magnetic saliency of the IPMSM has been achieved and commercialized. In this paper, an evaluation of the major techniques used for the sensorless control of the IPMSM has been presented, and their limitations have been clarified. Finally, the direction of future development of sensorless control is indicated.

In this paper a new rotor position observer for permanent magnet synchronous machines (PMSM) based on an Extended-Kalman-Filter (EKF) is presented. With this method, just one single EKF is sufficent to evaluate the position information from electromotive force (EMF) and anisotropy. Thus, the PMSM can be controlled for the entire speed range without a position sensor and without the need to switch or synchronize between different observers. The approach covers online estimation of permanent magnetic field and mechanical load. The resulting EKF-based rotor position estimator is embedded in the existing cascaded control concept of the PMSM without need of additional angle trackers or signal filters. The experimental validation for the position sensorless control shows optimized dynamic behaviour.
