At first, there are no wavelets in the wavelet layer; they are automatically generated in the online control process. In order to increase the convergence speed of the proposed controller, adaptive learning rates (ALRs) updated at each sampling time are used. In the online control process, no identifier is used to approximate the dynamic of the controlled plant, because of the learning ability of the proposed controller. Several simulations are used to demonstrate the effectiveness and adaptiveness of SCWNN.","PeriodicalId":22127,"journal":{"name":"Systems Science & Control Engineering: An Open Access Journal","volume":"9 1","pages":"261 - 267"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85273714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on these analysis, controlling of epileptic seizures, using a robust control method is considered. To this end we have utilized the mathematical model of cortical tissue activity. Chaotic behavior of this model is investigated through variations of pathological parameters. Utilization of two chaotic criteria known as entropy and largest Lyapunov exponents allowed us to monitor the chaotic behavior of the model during the reasearch. Moreover, both conniption and ending time of seizures are determined using chaotic analysis. The sliding mode method is used to design a robust controller with the purpose of controlling the seizures. The effectivness of the proposed method is shown via analysis and simulation results. Previous approches on controlling seazires did not considered robustness against the uncertainties. This problem is addressd here through designing a controller which is robust against system uncertainties. In addition to the guaranted finite time control of the seizures, consideration of the practical medical limitations for the control signal is another advantage of the proposed method.","PeriodicalId":22127,"journal":{"name":"Systems Science & Control Engineering: An Open Access Journal","volume":"16 1","pages":"216 - 227"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84346200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Time lags in reproduction and maturation of the organism are introduced in the system and conditions for local asymptotic stability of steady states are derived. The length of the delay preserving the stability is also estimated. It is found that there are stability switches for time delays, and Hopf bifurcations when time delays cross through some critical values. The stability and direction of the Hopf bifurcations are determined by applying the normal form method and the center manifold theory.

Reliability modeling of power transformers is very important for the electric grid design and risk assessment. In this paper, we propose a reliability model of power transformers with maintenance outage incorporated. The power transformer is divided into two groups of components described by different Markov state space models. Both types of state space models are combined to implement the whole power transformer modeling. Reliability indices such as probabilities of full, derated, and zero capacity as well as system unavailability are derived, and numerical evaluation of selected indices is presented with respect to different parameters. The developed models and analysis method are expected to serve as a useful component for the electric grid system design, assessment, and operation.","PeriodicalId":22127,"journal":{"name":"Systems Science & Control Engineering: An Open Access Journal","volume":"23 1","pages":"316 - 324"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91431813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since, the mass of fuel changes during the operation, both mass and the center of mass of the vehicle change with time. Therefore, dynamic equations are written around the center of buoyancy and these equations are more complicated than the equations of the fixed mass underwater vehicles. Also, fin angles which are means of path-following (control inputs) do not directly appear in the dynamical equations which cause more complexity in the controller design. In this paper, the multiple-modeling approach is used in the controller design and the control signals are achieved by the weighed combination of multiple controllers.
