A backup power supply system can provide electrical energy for load in harsh environment without grid, and plays a very important role natural disaster rescue military application. Compared with traditional sources, the proton-exchange membrane fuel cell has advantages of good low temperature start-up performance, noise, high efficiency density, no carbon emission, which gradually becomes main ...

Operation of the Golestan Dam Reservoir in Climate Change Conditions Using an Improved Multi-Objective Whale Optimization Algorithm

The high nonlinearity and time-varying coefficients characterize the elbow exoskeleton system for rehabilitation. To deal with these difficult control challenges, nonlinear reliable controllers are needed. This paper shows use of Sliding Mode Control (SMC) to track trajectory an Elbow Exoskeleton System (EES) presence parameter uncertainty. Whale Optimization Algorithm (WOA) algorithm is used t...

This paper presents a novel approach, based on the whale optimization algorithm (WOA), for channel estimation in wireless communication systems. The proposed method provides means to accurately estimate channel, while not requiring statistical characteristics of channel. uses WOA search best toward ultimate goal having smallest bit error rate (BER). approach is aimed at enhancing efficiency pil...

Metaheuristics are proven solutions for complex optimization problems. Recently, bio-inspired metaheuristics have shown their capabilities solving engineering The Whale Optimization Algorithm is a popular metaheuristic, which based on the hunting behavior of whale. For some problems, this algorithm suffers from local minima entrapment. To make WOA compatible with number challenging two major mo...
