This paper presents a sliding mode control (SMC) for the “full-bridge Buck inverter–DC motor” system when photovoltaic (PV) panel is considered as power supply. The executes trajectory tracking task related to angular velocity of DC motor shaft without need electromechanical sensors. proposed validated through realistic simulation results via Matlab-Simulink. In this regard, constructed by usin...

Despite attempts to increase the active power capability of vector-controlled voltage source converters (VSCs) connected very weak grids, interaction between control dynamics and physical system is not completely understood. The result often complex strategies that are difficult implement. This paper proposes an intuitive modification VSC based on considerations existing control. Several variab...

Hydraulic power take-off (HPTO) is considered to be one of the most effective schemes for wave energy conversion systems (WECs). The HPTO unit can constructed using standard hydraulic components that are readily available from industry market. However, construction and operation more complex rather than other types take-off, as many parameters need during optimization. Generator damping, motor ...

In quadruped robot locomotion using parallel mechanisms, researchers have used equal link lengths as legs for walking. However, force requirements are not the same in forward and return strokes. An unsymmetrical mechanism can be considered to accommodate such requirements. This work presents optimized dimensions of a 5R planar (5R-PPM) with two degrees freedom (DoF). Optimized determined by for...

Multi-rope elevators are widely used in modern buildings. However, problems such as vibration, noise, uneven wear of key components and shortened life caused by the distribution rope tensions still unsolved elevator industry. In order to balance different axial deformation each rope, a novel automatic equipment for rope-type (NABE-RE) is proposed this article. Simulations based on Simscape nume...

In this paper, a novel distributed nonlinear control strategy of mesh microgrids’ generators (DGs) based on droop approaches is proposed. It ensures secure synchronization DGs and their accurate active reactive power sharing in both islanded grid-connected operating modes microgrids. This method allows also seamless transition from to without affecting the DGs’ during as well controlling indepe...

The article aims to describe stages of development a mobile, anthropomorphic robot. individual phases the bio-inspired model-based design two-legged robot are described, from analysis human walking patterns, through creation simulation model and control system testing physical such is based on an movements parts lower body during locomotion. Based this analysis, chosen motion described as combi...

This paper presents the transient stability analysis of a pressurised water-type nuclear power plant following faults and disturbances affecting electricity grid to which it is connected. The modelled consists various integrated subsystems, such as core neutronics thermal-hydraulics, piping plenum, pressuriser, steam generator, turbine, governor, dynamics shaft, in addition turbine-speed contro...

Following the COVID-19 outbreak, redesign of an emergency mechanical pulmonary ventilator that is cheap and easily portable became necessary in several contexts, such as hotspots environments with poor resources. To address this important issue, a general multibody approach employed paper to develop reciprocating mechanism suitable for retrofitting existing manual ventilators through computer-a...

This letter studies aerobatic tic-toc control of quadcopters. Tic-toc enables rotorcraft to fly almost in the vertical plane rather than horizontal plane. It is one most challenging manoeuvrers achieve autonomously. The problem has our knowledge not yet been studied for Studying it could expand their flight envelope and improve performance extreme, tasks. In this letter, we employ a deep determ...
