Robust switched fractional controller for performance improvement of single phase active power filter

KRIM,D. CHIKOUCHE,A. BEDDAR

Frontiers in Energy 2016, Volume 10, Issue 2,   Pages 203-212 doi: 10.1007/s11708-015-0381-7

Abstract: The proposed switched fractional controller (SFC) consists of a conventional PI controller, a fractionalorder PI (FO-PI) controller and a decision maker that switches between them.Commonly, the conventional PI controller is used in regulation loops due to its advantages in steady-stateOn the other hand, the FO-PI controller overcomes these drawbacks but it causes dramatic degradationThus, the purpose of this paper is to switch to the PI controller in steady-state to obtain the best

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 2,   Pages 180-191 doi: 10.1631/FITEE.1601543

Abstract: We propose a novel approach called the robust fractional-order proportional-integral-derivative (FOPID) controller, to stabilize a perturbed nonlinear chaotic system on one of its unstable fixed points.We extract an initial set of controller parameters, which are subsequently optimized using a quadraticThe integral and derivative fractional orders are also identified by this quadratic criterion.PIλDμ controller provides the best closed-loop system performance in stabilizing the unstable fixed

generating system integration on frequency stabilization in multi-area power system with fuzzy logic controller

D. MATHUR,H. SIGUERDIDJANE

Frontiers in Energy 2015, Volume 9, Issue 1,   Pages 7-21 doi: 10.1007/s11708-014-0338-2

Abstract: Among the available options for renewable energy integration in existing power system, wind power is being considered as one of the suited options for future electrical power generation. The major constraint of wind power generating system (WPGS) is that it does not provide inertial support because of power electronic converters between the grid and the WPGS to facilitate frequency stabilization. The proposed control strategy suggests a substantial contribution to system inertia in terms of short-term active power support in a two area restructured power system. The control scheme uses fuzzy logic based design and takes frequency deviation as input to provide quick active power support, which balances the drop in frequency and tie-line power during transient conditions. This paper presents a comprehensive study of the wind power impact with increasing wind power penetration on frequency stabilization in restructured power system scenario. Variation of load conditions are also analyzed in simulation studies for the same power system model with the proposed control scheme. Simulation results advocates the justification of control scheme over other schemes.

RGS16 regulated by let-7c-5p promotes glioma progression by activating PI3K-AKT pathway

Frontiers of Medicine 2023, Volume 17, Issue 1,   Pages 143-155 doi: 10.1007/s11684-022-0929-y

Abstract: Gliomas are the most common central nervous system tumours; they are highly aggressive and have a poor prognosis. RGS16 belongs to the regulator of G-protein signalling (RGS) protein family, which plays an important role in promoting various cancers, such as breast cancer, pancreatic cancer, and colorectal cancer. Moreover, previous studies confirmed that let-7c-5p, a well-known microRNA, can act as a tumour suppressor to regulate the progression of various tumours by inhibiting the expression of its target genes. However, whether RGS16 can promote the progression of glioma and whether it is regulated by miR let-7c-5p are still unknown. Here, we confirmed that RGS16 is upregulated in glioma tissues and that high expression of RGS16 is associated with poor survival. Ectopic deletion of RGS16 significantly suppressed glioma cell proliferation and migration both in vitro and in vivo. Moreover, RGS16 was validated as a direct target gene of miR let-7c-5p. The overexpression of miR let-7c-5p obviously downregulated the expression of RGS16, and knocking down miR let-7c-5p had the opposite effect. Thus, we suggest that the suppression of RGS16 by miR let-7c-5p can promote glioma progression and may serve as a potential prognostic biomarker and therapeutic target in glioma.
