A robust control algorithm is always needed to harvest maximum power from a Wind Energy Conversion System (WECS) by operating it consistently at Maximum Power Point (MPP) in the presence of wind speed variations. In this work, Tracking (MPPT) designed via Conventional Sliding Mode Control (CSMC), Super Twisting Algorithm (STA), and Real (RTA) applied Permanent Magnet Synchronous Generator (PMSG...

In this paper, two new versions of modified active disturbance rejection control (MADRC) are proposed to stabilize a nonlinear quadruple tank system and the water levels lower tanks in presence exogenous disturbances, parameter uncertainties, parallel varying input set-points. The first scheme is configured from combination tracking differentiator (TD), super twisting sliding mode (STC-SM), ext...

It is difficult to model and determine the parameters of steer-by-wire (SBW) system accurately, perturbation variable with complex changeable tire–road conditions. In order improve control performance vehicle SBW system, an adaptive fast super-twisting sliding mode (AFST-SMC) scheme time-delay estimation (TDE) proposed. The proposed uses TDE acquire lumped dynamics in a simple way establishes p...

Method. The main role indirect control is to regulate powers for variable speed dual-rotor wind systems. field-oriented a classical scheme simple structure. Pulse an adaptive-network-based fuzzy inf...

By defining an extended BRST operator that includes the chiral part of N=2 global supersymmetry, it is shown that the full N=2 offshell Super Yang Mills Action can be represented as an exact BRST term. The action written in this form suggests that the fields of the Topological Yang Mills theory can be defined in terms of composite fields of supersymmetry ghosts and N=2 fields in a natural way. ...

In this paper, a full-bridge boost power converter topology is studied for power factor control, using output higher order sliding mode control. The AC/DC converters are used for charging the battery and super-capacitor in hybrid electric vehicles from the utility. The proposed control forces the input currents to track the desired values, which can controls the output voltage while keeping the...

Edwards’ elliptic curve form is popular in modern cryptographic implementations thanks to their fast, strongly unified addition formulas. Twisted Edwards curves with a = −1 are slightly faster, but their addition formulas are not complete over Fp where p ≡ 3 (mod 4). In this short note, we propose that designers specify Edwards curves, but implement scalar multiplications and the like using an ...
