Research on Control Strategy of Permanent Magnet Synchronous Motor Based on Fast Terminal Super-Twisting Sliding Mode Observer
The sliding mode observer (SMO) has the advantages of small influence by parameter changes and strong robustness, which is widely used in the sensorless control of permanent magnet synchronous motor (PMSM). However, when the sliding mode observer is used to observe the position and speed information of the PMSM, the problem of slow response and excessive chattering is always accompanied. In order to reduce the time of observation position and improve the anti-interference of the system, the super-twisting sliding mode observer(STSMO) is proposed, which can be used to reduce the chattering amplitude effectively, Additionally, the fast and terminal factors is added to the sliding mode surface so that it can converge quickly in a finite time. Then, an improved fast terminal super-twisting sliding mode observer (FTSTSMO) is proposed in the extended state. It can be proved that the observer can converge by Lyapunov stability, and the new observer can suppress chattering and improve the convergence speed. Finally, the experimental analysis is carried out on the 1kW permanent magnet synchronous motor experimental platform, and the SMO and STSMO are compared with FTSTSMO. The results show that FTSTSMO can effectively reduce the fluctuation of the system, improve the tracking effect of rotor speed and rotor position when the speed changes, and further make the whole control system of PMSM have stronger robustness and stability.

期刊介绍:
IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest.
IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on:
Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals.
Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering.
Development of new or improved fabrication or manufacturing techniques.
Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
