Simplified Rotor and Stator Resistance Estimation Method Based on Direct Rotor Flux Identification
Mingyu Wang,Dafang Wang,Guanglin Dong,Hui Wei,Xiu Liang,Zexu Xu 전력전자학회 2019 JOURNAL OF POWER ELECTRONICS Vol.19 No.3
Since parameter mismatch seriously impacts the efficiency and stability of induction motor drives, it is important to accurately estimate the rotor and stator resistance. This paper introduces a method to directly calculate the rotor flux that is independent of stator and rotor resistance and electrical angle. It is based on obtaining the rotor and stator resistance using the model reference adaptive system (MRAS) method. The method has a lower computation burden and less adaptation time when compared with other rotor resistance estimation methods. This paper builds three coordinate frames to analyze the rotor flux error and rotor resistance error. A number of implementation issues are also considered.

AC092127.1-miR-451a-AE binding protein 2 Signaling Facilitates Malignant Properties of Breast Cancer

Purpose: The purpose of the current study was to explore the functions and potential mechanism of miR-451a in breast cancer (BC). Methods: Quantitative reverse transcription real-time polymerase chain reaction was used to analyze the expression of miR-451a in human normal mammary cells (MCF-10A) and BC cells. Colony formation assay, terminal-deoxynucleoitidyl transferase mediated nick end labeling assay and transwell assays were conducted to validate the effect of miR-451a on proliferation, apoptosis, migration and invasion of BC cells, respectively. RNA pull-down, RNA immunoprecipitation and luciferase reporter assays were applied to investigate the upstream and downstream mechanisms of miR-451a in BC cells. Results: MiR-451a was expressed at a low level in BC cells. Overexpression of miR-451a repressed BC cells proliferation, migration and invasion. Moreover, long non-coding RNA AC092127.1 acted as a sponge of miR-451a to enhance the expression level of AE binding protein 2 (AEBP2) that was demonstrated to be the target gene of miR-451a in BC cells. Finally, rescue experiments validated that miR-451a and AEBP2 involved in AC092127.1-mediated BC cell growth, migration and invasion. Conclusion: In a word, AC092127.1/miR-451a/AEBP2 axis contributes to BC cell growth, migration and invasion. Our results may help to find novel potential targets for BC treatment.
