This paper presents a novel algorithm based on particle swarm optimization (PSO) to estimate the states of electric distribution networks. In order to improve the performance, accuracy, convergence speed, and eliminate the stagnation effect of original PSO, a secondary PSO loop and mutation algorithm as well as stretching function is proposed. For accounting uncertainties of loads in distributi...
In this paper, the design of a distributed adaptive controller for a class of unknown non-affine MIMO strict-feedback multi agent systems with time delay has been performed under a directed graph. The controller design is based on dynamic surface control method. In the design process, radial basis function neural networks (RBFNNs) were employed to approximate the unknown nonlinear functions. S...
Loops in programs are the source of many optimizations for improving program performance, particularly on modern high-performance architectures as well as vector and multithreaded systems. Techniques such as loop invariant code motion, loop unrolling and loop peeling have demonstrated their utility in compiler optimizations. However, many of these techniques can only be used in very limited cas...
آنالیز شبکه های آبرسانی یکی از مسائل بسیاز جذابی است که از چند دهه قبل تاکنون مختصصان علوم آب را به خود مشغول کرده است و آنها را بر آن داشته است که ابداع روشهای جدید تحلیل، تا حدودی معایب روشهای قبل را بهبود بخشند. برنامه های کامپیوتری گوناگونی جهت تحلیل شبکه های آبرسانی تهیه شده است که از معروفترین آنها می توان از exkypipe-net-loop و بالاخره برنامه جدید e.b.e نام برد. این رساله در حالتهای خاصی...
this article presents a fuzzy robust mixed - sensitivity gain - scheduled h controller based on the loop -shaping methodology for a class of mimo uncertain nonlinear time - varying systems. in order to design this controller, the nonlinear parameter - dependent plant is first modeled as a set of linear subsystems by takagi and sugeno’s (t - s) fuzzy approach. both loop - shaping methodology and...
this paper considers the problem of stable limit cycles generating in a class of uncertain nonlinear systems which leads to stable oscillations in the system’s output.this is a wanted behavior in many practical engineering problems. for this purpose, first the equation of the desirable limit cycle is achieved according to shape, amplitude and frequency of the required output oscillations. then,...
