Based on the back pressure calculation model, influence on back pressure variation by adjusting circulating water flow is discussed in this paper. The model is developed from mechanism analysis of the condenser and cooling tower. Results show that cooling water inlet temperature is an important parameter during the back pressure calculation. Changing the unit output by adjusting circulating cooling water flow of the cold-end system has different effects on the unit output increment and decrement.","PeriodicalId":169447,"journal":{"name":"2013 Fifth International Conference on Measuring Technology and Mechatronics Automation","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126883178","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}

Microtopography was detected in the simulative environment of deep-sea mining, Three kinds of typical reverberations were acquired in different working conditions. Phase space reconstruction parameters of the reverberations are estimated. The largest Lyapunov exponents of the reverberations also are calculated in phase space, the largest Laypunov exponents are greater than 0 and less than 0.1. In contrast to white Gaussian noise, this paper demonstrates the chaotic dynamics of reverberations generated from microtopography detection in the deep-sea mining complex environment. The results provide a new approach of nonlinear dynamics to model and process reverberation generated from short distance and high frequency acoustic detection in deep-sea mining complex environment.","PeriodicalId":169447,"journal":{"name":"2013 Fifth International Conference on Measuring Technology and Mechatronics Automation","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124350682","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}

Correlation analysis is applied firstly to establish autoregressive model. Then weights of Auto encoder can be obtained by improved differential evolution (DE) algorithm. Meanwhile, the least square method is used to prune nodes every layer to simplifying network structure. Features of training sample and reconstruction residuals can be extracted by DAutoencoder. Monitoring statistic is developed and confidence limit is computed by kernel density estimation at last. According to correlation between measured variables and nonlinear features, the contribution of each variable is calculated to give contribution plots. Simulation results of Tennessee Eastman (TE) process show that DAutoencoder-based method is more effective than KPCA (Kernel Principal Component Analysis) for process monitoring, and it can also realize fault identification.","PeriodicalId":169447,"journal":{"name":"2013 Fifth International Conference on Measuring Technology and Mechatronics Automation","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127839489","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}
