Swarm intelligence (SI) is the collective behavior of decentralized , self-organized systems, natural or artificial. SI systems are typically made up of a population of simple agents interacting locally with one another and with their environment. The inspiration often comes from nature, especially biological systems. The agents follow very simple rules,(More)

This paper presents a robust DC motor speed controller based on the concept of fractional-order PID (FOPID or PI D λ µ) controllers. The method for tuning the PI D λ µ controller uses the Bode envelopes of the control systems with parametric uncertainty. The uncertainty caused by the parameter changes of DC motor are formulated as five different design(More)
In this paper, a sliding mode control law is designed for stabilization of specific class of linear systems of fractional order despite of multi delays in the state system. A fractional order sliding surface is proposed, and using the variable structure control theorem, control law is introduced. A numerical simulation is given to show the effectiveness of(More)
In this paper, a sliding mode controller is proposed for synchronization of fractional-order chaotic systems in the presence of uncertainty. First, a class of three-dimensional fractional-order chaotic systems has been studied and then sliding mode controller is designed to guarantee asymptotically stable presence of uncertainty. In addition, control of(More)
Synchronization of chaos has widely spread as an important issue in nonlinear systems and is one of the most important branches on the problem of controlling of chaos. In this paper, among different chaotic systems the economy chaotic system has been selected. The main aim of this paper is the designing based on the active sliding mode control for the(More)
Soft computing (SC) obtains inexact solutions to computa-tionally hard tasks such as the NP-complete problems, for which there is no known algorithm that can obtain an exact solution in polynomial time. SC differs from conventional hard computing (HC) in that SC is tolerant of imprecision, uncertainty, partial truth, and approximation. Recently, SC has(More)
In this paper, the execution of some features based on wavelet transform are evaluated through classification of audio to speech and music using the MLP classifiers Optimized by Genetic Algorithm. Classification results show the wavelet features are completely successful in speech/music classification. Experimental comparisons using different wavelets are(More)
