In this paper, we firstly propose a method of triangulation to perform SCPLNN approximation. Our scheme starts with an initial, coarse triangulation of the given data and subdivides simplex until the error of the SCPLNN approximation is smaller than some tolerance. Then SCPLNN based on triangulation is identified. The proposed method involving triangulation and identification of SCPLNN is shown to be useful in approximating nonlinear systems. In addition, for each simplex, the local inverse model can easily be calculated for each local model of SCPLNN is linear. From control perspective, we exploit the advantage of the piecewise linear property of SCPLNN and design controllers for each approximate model. The validity of this control scheme using inverse of the local linear model is tested by using a NARX model.","PeriodicalId":342070,"journal":{"name":"2008 IEEE International Symposium on Intelligent Control","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132404767","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 this paper, we investigate deterministic learning of discrete-time nonlinear systems. For periodic or recurrent dynamical patterns, the persistent excitation (PE) condition can be satisfied by a regression subvector constructed from the neurons near the sequence. With the satisfaction of the PE condition, it is shown that the internal dynamics of an uncertain discrete-time nonlinear system can be accurately learned along the state sequence. Using the learned knowledge, a rapid pattern recognition mechanism can be implemented, in which synchronous errors are taken as the measure of similarity of the dynamical patterns generated from different systems. Compared with the methods based on signal processing, this approach appears to need less time-domain information for recognition and is more effective for high speed applications. Simulation is included to show the effectiveness of the approach.","PeriodicalId":342070,"journal":{"name":"2008 IEEE International Symposium on Intelligent Control","volume":"97 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113960706","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 multi-model scheme is composed of three models of increasing consecutive orders operating in parallel along with a switching mechanism between them. The switching policy selects on-line the necessary order of the nominal model required to achieve the desired degree of performance of the closed-loop depending on the reference signal selection. In this way, the order selection is performed automatically in real-time by comparing the actual behaviour of the system with the desired performance for the closed-loop. The estimation of the parameters of the model is performed by an adaptive algorithm integrating a so-called multi-estimation scheme. This architecture leads to a simple procedure to on-line select the appropriate order of the nominal model required for a certain control application with assessment of a prescribed level of closed-loop performance.","PeriodicalId":342070,"journal":{"name":"2008 IEEE International Symposium on Intelligent Control","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116903617","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 MFD problem is described by a bipartite diagnosis graph (BDG) which consists of a set of components, a set of alarms, and a set of connections (or causal dependencies) between them, along with a set of parameters that describe the prior probabilities for component, alarm and connection failures. Given the alarm observations, our goal is to find the status of the components that has the maximum a posteriori (MAP) probability. By using properties of the max-product algorithm (MPA) and the sequential max-product algorithm (SMPA), we are able to analyze in this paper the performance of both algorithms with respect to the MAP solution (in terms of the probability of erroneous diagnosis). Our theoretical analysis indicates that the upper bounds in this paper are up to several orders of magnitude better than existing bounds, especially when the smallest loop size is an odd number. We also provide examples which demonstrate that our theoretical upper bounds match very well with simulation results.","PeriodicalId":342070,"journal":{"name":"2008 IEEE International Symposium on Intelligent Control","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128663851","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}

Although a number of different ways using ultrasonic beacons have been developed, these methods are restricted to a relatively small area because all the beacons should be localized before any actual measurement. In this paper, a new methodology is developed to improve the accuracy of the auto-calibration process in the localization method. The new three-point-extraction algorithm is used in conjunction with existing trilateration and auto-calibration algorithms to compose a new localization method. Validity of the new algorithm is verified through experiments for two and three triangular areas, where the localized path error is confirmed to be significantly small in average. In addition, the path error turns out not to accumulate to a considerable extent. The result enables the robot to autonomously localize its path by recognizing the accurate positions of newly appearing beacons.","PeriodicalId":342070,"journal":{"name":"2008 IEEE International Symposium on Intelligent Control","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133813664","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}
