The modelling is based on the neural network autoregressive with exogenous input structure. During the network training, the optimisation of the network weights has been carried out by minimisation the error through the Levenberg-Marquardt algorithm (LMA). In the weight decay regularisation network training, the LMA has been modified. Several results on unregularised and regularised trainings have been presented, compared and concluded. The results showed that the optimal weights are obtained with the moderate regularisation of the network training.","PeriodicalId":338469,"journal":{"name":"2009 5th International Colloquium on Signal Processing & Its Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125838145","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}

As precise instrument tools are usually conveyed with this kind of cranes, it is essential to control the vibrations during the motion. This paper deals with the control of the crane's angle during the motion. Basically, the goal of the paper is find the exact position of the load. Since the load is hanged by a flexible rope, using angles sensor can not be accurate. Hence, the use of a camera can provide the simplest technique for this purpose.","PeriodicalId":338469,"journal":{"name":"2009 5th International Colloquium on Signal Processing & Its Applications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114922244","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}
