ystem identification is mainly the process of improving a mathematical modeling of a physical system using experimental data. In this paper, a new hybrid wavelet neural network is proposed for the system identification purposes. The Gravitational Search Algorithm (GSA) is a new evolutionary algorithm which recently introduced and has a good performance in different optimization problems. The GS...

The insertion of distributed generator (DG) into distribution systems for performance improvement has been an obvious application. But the choice of DG has been extended to the networked systems as well in the recent years. The penetration level of DG is accelerating due to the liberalization of electricity markets and Technological advances in small generators and energy storage devices. In th...

In this paper, the gravitational search algorithm (GSA) is proposed as a method for controlling opening and closing of airplane wing tires. The GSA used to find optimum proportional-integral-derivative (PID) controller, which controls tires during take-off landing. addition, suggested an approach overcoming absence transfer function, usually required design PID. use expected improve system. Two...

In this paper, the modified linearized Phillips-Heffron model is utilized to theoretically analyze asingle-machine infinite-bus (SMIB) installed with SSSC. Then, the results of this analysis are used forassessing the potential of an SSSC supplementary controller to improve the dynamic stability of apower system. This is carried out by measuring the electromechanical controllability through sing...

This work proposes an effective synergy of the Intervals' Number k-nearest neighbor (INknn) classifier, that is a granular extension of the conventional knn classifier in the metric lattice of Intervals' Numbers (INs), with the gravitational search algorithm (GSA) for stochastic search and optimization. Hence, the gsaINknn classifier emerges whose effectiveness is demonstrated here on 12 benchm...

Data clustering is one of the most popular techniques of information management, which is used in many applications of science and engineering such as machine learning, pattern reorganization, image processing, data mining, and web mining. Different algorithms have been suggested by researchers, where the evolutionary algorithms are the best in data clustering and especially in big datasets. It...

In this work, a chaotic search-based hybrid Sperm Swarm Optimized-Gravitational Search Algorithm (CSSO-GSA) is proposed for automatic load frequency control (ALFC) of power system (HPS). The HPS model developed using multiple sources (thermal, bio-fuel, and renewable energy (RE)) that generate to balance the system’s demand. To regulate system, parameters proportional-integral-derivative (PID) ...

Abstract A Falling Weight Deflectometer is popular equipment to measure surface deflections under imposed loadings, providing the necessary parameters for back-calculating elastic moduli of road pavements. There are several back-calculation programs available that accurately back-calculate pavement layer moduli. The Gravitational Search Algorithm (GSA), a metaheuristic optimization algorithm in...
