In this article whale optimization algorithm (WOA) has been applied to solve the combined heat and power economic dispatch (CHPED) problem. The CHPED is energy system which provides both power. Due presence of valve point loading prohibited working region, problems become more complex one. main objective problem minimize total cost fuel as well with fulfill load demand. This technique shows sev...

Abstract Beluga whale optimization (BWO) algorithm is a recently proposed population intelligence algorithm. Inspired by the swimming, foraging, and falling behaviors of beluga populations, it shows good competitive performance compared to other state-of-the-art algorithms. However, original BWO faces challenges unbalanced exploration exploitation, premature stagnation iterations, low convergen...

The optimal reactive power dispatch (ORPD) is a complex, non-meritorious control issue with continuous and discontinuous variables. This article exhibits whale optimization algorithm (WOA) motivated by the whale’s bubble-net hunting tactic to resolve ORPD. intention comply certain constraints promote voltage transmission quality adequately altering parameters. WOA not only equalizes exploitatio...

The quantity of network attacks and the harm from them is constantly increasing, so detection these an urgent task in information security field. In this paper, we investigate approach to building intrusion systems using a classifier based on fuzzy rules. process creating given set input output data can be presented as solution problems clustering, informative features selection, parameters rul...

A discrete whale optimization algorithm (DWOA) is presented to solve the no-wait flow shop scheduling problem (NWFSSP) with objective makespan. An effective combination of nearest neighbor (NN) and standard deviation heuristics (SDH) used acquire initial solutions population. After that, three crossover operators, two-point (TPX), multiple-point (MPX) job-based (JBX) are designed mimics humpbac...

Physiotherapeutic exoskeleton devices have recently been developed to help people rehabilitate impaired limb mobility and replace the use of physiotherapists. Such systems are characterized by high nonlinear time-varying coefficients. In order cope with such difficult control challenges, a need arose for reliable controllers. While in this study Sliding Mode Control (SMC) was used track traject...

In this paper a robust fractional order PID (FOPID) controller is proposed to control the automatic voltage regulator (AVR) system, tuning of gains are done using whale optimization algorithm (WOA) and integral time absolute error (ITAE) cost function adopted achieve an efficient performance. The transient analysis was compared with conventional in terms overshoot, settling time, rise peak expl...
