Introduction. Sailing is a sport that places high demands on the physical fitness of an athlete. Despite fact this has been practiced for very long time, experts have not paid due attention to assessing impact athlete’s load during training his fatigue. The use mathematical modeling methods at stage athletes select optimal will make more effective. In order determine method, which allow quite s...

in this paper, a novel approach for control of the dc-dc buck converter in high-power and low-voltage applications is proposed. designed method is developed according to state feedback linearization based controller , which is able to stabilize output voltage in a wide range of operation. it is clear that in high-power applications, parasitic elements of the converter may become comparable with...

the use of renewable energy in power generation and sudden changes in load and fault in power transmission lines  may cause a voltage drop in the system and challenge the reliability of the system. one way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. the use of ener...

in this paper, finding dynamic load carrying capacity (dlcc) of flexible link manipulators in point to-point motion was formulated as an optimal control problem. the finite element method was employed for modelling and deriving the dynamic equations of the system. the study employed indirect solution of optimal control for system motion planning. due to offline nature of the method, many diffic...

Load balancing plays a critical role in efficiently dispatching jobs parallel-server systems such as cloud networks and data centers. A fundamental challenge the design of load algorithms is to achieve an optimal trade-off between delay performance implementation overhead (e.g. communication or memory usage). This has primarily been studied so far from angle amount required asymptotically perfo...

Increasing of word demand load caused a new Distributed Generation (DG) to enter to powersystem. One of the most renewable energy is the Photovoltaic System. It is beneficial to use thissystem in both separately as well as connected to power system using power electronics interface.In this paper an optimal PID controller for Photovoltaic System systems has been developed. Theoptimization techni...
