An example of a lattice-based AMN is the Cerebellar Model Articulation Controller (CMAC) neural network. A hierarchical multi-resolution lattice approach is proposed and investigated through experimentation as a possible approach to alleviate the main drawback of AMNs: the required storage is an exponential function of the number of inputs.

It includes information about voltage in the current loop. Its main features are stable operation over full range of duty cycle variations without subharmonic oscillations, fast dynamic response and inherent short-circuit protection. Therefore, no artificial means of stabilizing should be provided as with peak current-mode control. Excellent dynamic response is achieved compared to other existing control methods. Implementation is simple and advantageous. Since the power converter is of a discrete nature, its sampled-data model is analyzed and small-signal analysis is performed. An experimental model of a buck power converter is tested, and the results of its transient response are obtained. Boost and buck-boost power converters are analyzed and their results are briefly reviewed.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124361087","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}

A set of possible voltages is selected so that an equation with a time integral considered within a sampling period should be satisfied every sampling time. The simulation results show that the proposed control scheme produces good characteristics comparable to a conventional method of using a set of triangular carriers in some performance criteria such as unity power factor, low harmonic distortion of input current and voltage balancing of two series-connected DC capacitors.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114714701","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}

The economic issues related to roll-eccentricity are very important. Often, after the rolling of a strip, the mill operators find the thickness measured by the X-ray meter at the exit of the FHSM is not up to desired quality standards, with the cost that this implies. In this case, the operator must diagnose which stands have produced the thickness problems. The solution is to change the rolls in the problematic stand. The diagnosis of which stand is responsible for the defects must be fast and reliable, because meanwhile the mill must stop production. Furthermore, analyzing the historical values of individual stand influence, it is possible to prevent failures of quality thickness. A novel method of diagnosis based on observers and pattern matching using fuzzy technology has been developed. Nevertheless, the high computational cost of the solution requires multiprocessor-based equipment to accomplish the real-time constraints.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"335 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124704679","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}
