This paper proposes a new method of sliding mode base controller for shunt active power filter to compensate the harmonic currents of a load. In this controller there isn't any need to PI DC voltage controller to regulate the DC capacitor voltage of shunt active power filter. In this method, first the reference currents of shunt active power filter that should be tracked to reduce or eliminate ...

This paper proposes a stand-alone photovoltaic (PV) system based on a DC-DC positive output super lift Luo (POSLL) converter. A conventional sliding mode control, a sliding mode controller using a simple sign function and a linear controller using proportional integrator (PI) are used for the control of the PV panel voltage and POSLL converter inductor current and these methods are compared tog...

This paper presents a new approach used for switched reluctance motors (SRM) speed control. Two nonlinear controller, one is variable structure with sliding mode controlled type (VSC) and the other is PI-like fuzzy controller (FLC), define a new control structure. The VSC acts mainly in a transient state which is increasing system stability limits. But, PI-like FLC controller acts in the steady...

In this work, we studied the mechanical and thermal stability of ~100 nm Pd thin films magnetron sputter deposited on a bare oxidized Si(100) wafer, sputtered Titanium (Ti) intermediate layer, spin-coated Polyimide (PI) layer. The dependence film morphology film-substrate interaction was investigated. It shown that columnar with elongated voids at part grain boundaries is resistant to embrittle...

The sustainable development of early childhood institutions in aging China calls for the teachers, which should attend to balanced between male and female teachers. Yet this issue has not been adequately investigated literature. To fill research gap, study explored gender differences Chinese (EC) teachers’ professional identity (PI) emotional labor strategies. Altogether, 250 teachers (146 104 ...

Synchrotron radiation-based x-ray photoemission spectroscopy was used to study the surface Fermi level position within the band gap for thin metal overlayers of Au, Al, Ni, Ti, Pt, and Pd on n–GaN and p–GaN. Nonequilibrium effects were taken into account by measuring the Fermi edge of the metal overlayer. There are two different behaviors observed for the six metals studied. For Au, Ti, and Pt,...

This paper investigates the robust ∞ H sliding mode control problem for a class of uncertain switched delay systems. A single sliding surface is constructed such that the reduced-order equivalent sliding motion restricted to the sliding surface is completely invariant to all admissible uncertainties. For cases of known delay and unknown delay, the existence conditions of the sliding surface are...

An investigation of the friction and sliding wear of gray cast iron against chromium plated cast irons was carried out on a newly constructed reciprocating friction and wear tester. The tests were the first to be done on the test rig under dry conditions and at the speed of 170 cm/min, and variable loads of 20-260 N for a duration of 15 min. to 3 hours. The gray cast iron surfaces worn by a pro...

This paper deals with the application of artificial neural network (ANN) and fuzzy based Adaptive Neuro Fuzzy Inference System(ANFIS) approach to Load Frequency Control (LFC) of multi unequal area hydro-thermal interconnected power system. The proposed ANFIS controller combines the advantages of fuzzy controller as well as quick response and adaptability nature of ANN. Area-1 and area-2 consist...

Pediocin PD-1 is a ribosomally synthesized antimicrobial peptide produced by Pediococcus damnosus NCFB1832. It inhibits the growth of several food spoilage bacteria, including malolactic bacteria isolated from wine. Pediocin PD-1 is 2866.87+/-0.4 Da in size, has an isoelectric point (pI) of ca. 9.0 and, on amino acid composition, has partial homology to the lantibiotic plantaricin C. The highes...
