A \u0000comparative analysis of several popular models, which calculate interval \u0000weights on the basis of interval pairwise comparison matrices (IPCMs), was \u0000performed. The features of these models when they are applied to IPCMs with \u0000different inconsistency levels were identified. An algorithm is proposed which \u0000contains the stages for analyzing and increasing the IPCM inconsistency, \u0000calculating normalized interval weights, and calculating the ranking of \u0000decision alternatives on the basis of the resulting interval weights. It was \u0000found that the property of weak order preservation usually allowed identifying \u0000order-related intransitive expert pairwise comparison judgments. The correction \u0000of these elements leads to the removal of contradictions in resulting weights \u0000and increases the accuracy and reliability of results.","PeriodicalId":62904,"journal":{"name":"智能控制与自动化(英文)","volume":"07 1","pages":"39-54"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70626261","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}

In contrast with the traditional \u0000roadmap-based algorithms, our proposed algorithm is designed to use minimal \u0000sensory data instead of costly ones. Therefore, we adopt a dynamic data \u0000structure called Gap Navigation Trees (GNT), which keeps track of the depth \u0000discontinuities (gaps) of the local environment. It is incrementally \u0000constructed as the robot which navigates the environment. Upon exploring the \u0000whole environment, the resulting final data structure exemplifies the roadmap \u0000required for further processing. To avoid infinite cycles, we propose to use \u0000landmarks. Similar to traditional roadmap techniques, the resulting algorithm \u0000can serve key applications such as exploration and target finding. The \u0000simulation results endorse this conclusion.

Based on the literature review, time delay switch (TDS) attacks could make any control system, in particular a power control system, unstable. Therefore, future smart grids will have to use advanced methods to provide better situational awareness of power grid states keeping smart grids reliable and safe from TDS attacks. Here, we introduce a simple method for preventing time delay switch attack on networked control systems. The method relies on an estimator that will estimate and track time delays introduced by an adversary. Knowing the maximum tolerable time delay of the plant’s optimal controller for which the plant remains stable, a time-delay detector issues an alarm signal when the estimated time delay is larger than the minimum one and directs the system to alarm state. In an alarm state, the plant operates under the control of an emergency controller that is local to the plant and remains in this mode until the networked control system state is restored. This method is an inexpensive and simple way to guarantee that an industrial control system remains stable and secure.","PeriodicalId":62904,"journal":{"name":"智能控制与自动化(英文)","volume":"06 1","pages":"205-214"},"PeriodicalIF":0.0,"publicationDate":"2015-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70625857","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}

In recent years, an interesting alternative to other machine types has been chosen for traction applications especially starter-generator. Their rotors do not generate significant heat, resulting in easy cooling. Their unidirectional flux and current may generate lower core losses and require a simple converter design. Moreover, the switched reluctance machines are known for their high reliability and capability of operating in four quadrants for a variable speed drive. Despite those merits, switched reluctance machine has not been extensively used until recently because of its problems of torque ripples and noise. Additionally, researchers have faced many difficulties to build a SRM model because it is inherently multivariable. It has strong coupling and especially a high nonlinearity. In this paper, we deal with many modeling methods. Numerical, analytical and intelligent approaches are studied. The important aim in this research is to use static results from FEMM simulation as flux-linkage, co-energy, static torque to form a dynamic model of a switched reluctance machine used next as a starter-generator of a hybrid vehicle.","PeriodicalId":62904,"journal":{"name":"智能控制与自动化(英文)","volume":"06 1","pages":"271-288"},"PeriodicalIF":0.0,"publicationDate":"2015-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70625523","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}
