Three emerging and selected topics in PMSM drives, including sensorless control, electrolytic capacitorless control and parameter identification, are to be presented in this tutorial. This tutorial is available for specialists in power electronics and AC motor drives. The tutorial aims to introduce the technical knowledge from both academia and industry perspectives.
Learning objectives:
Permanent magnet synchronous machine (PMSM) has been applied in the wide spectrum of industry including but not limited to renewable energy, transportation, military, and medical systems, thanks to the advantages of high power density and high efficiency. Recently, large effects have been devoted towards the high-performance PMSM drives. Three emerging and selected topics in PMSM drives, including sensorless control, electrolytic capacitorless control and parameter identification, are to be presented in this tutorial.
Basically, there are two main types of sensorless PMSM control according to the working frequency: one is model based method which detects the fundamental component of back electromotive force (EMF); the other injects additional excitation signal to utilize the asymmetrical effect of inductance in PMSM, which had opened new horizon of sensorless control of PMSM. However, the additional side effects such as electromagnetic interference and extra acoustic noise impose restrictions on the extensive application of this method. Lots of endeavors have been made to diminish the acoustic noise introduced by the injected signals as much as possible. Recently, pseudorandom (PR) signal injection, including PR frequency injection, PR phase injection, and hybrid PR injection, has emerged and been applied to sensorless drives to get rid of these side effects.
Besides, with the development of modern PMSM drive, the lifetime and cost have become important issues. Aluminum electrolytic capacitors are widely used in air conditioning compressor drives because of the larger capacity and higher cost performance, whereas their lifetime is closely related to the environment temperature, which has become one of the main weakness. The electrolytic capacitorless drive adopting the small film capacitor instead of DC-link electrolytic capacitor can significantly improve the operating lifetime. At present, there are still some technical difficulties in the electrolytic capacitor-less PMSM drives in industry application, such as harmonic regulation. The above technique will be reported in this tutorial. Effective solution will be proposed, which benefits promoting the electrolytic capacitorless drive applications.
Finally, the high-performance control state detection of PMSM strongly depend on accurate parameter information, so the parameter identification of PMSM is of great significance. This tutorial presents several approaches to meet the parameter identification requirements in different PMSM working condition. The offline identification strategies are presented, which takes the inductance variation under different saturation states into account. As for the online parameter identification, the influence of model deficient rank and parameter coupling is analyzed. Then, an impedance-based model is introduced to deal with those problems in existing identification methods. Furthermore, a minimum current vector scanning method is presented to reduce the identification error of inaccurate estimated rotor position under sensorless control. In order to improve the accuracy of parameter identification, the analysis of diver nonideal characteristics is presented as well as the corresponding compensation strategies.
Target audience and prerequisite knowledge of audience:
This tutorial is available for specialists in power electronics and AC motor drives. The tutorial aims to introduce the technical knowledge from both academia and industry perspectives. By the end of this tutorial, audiences would benefit from three typical topics in PMSM drives, including sensorless control, electrolytic capacitorless control and parameter identification.
