It's particularly crucial to monitor the battery state of health and prognosis the battery remaining useful life (RUL). Considering the highly linear correlation between capacity and the changing rate of temperature (TR), a new RUL prediction approach is proposed which provides a better description on the capacity degradation based on the changing rate of battery temperature and cycle number N. First a binary linear regress model is proposed for battery state of health (SOH) and RUL prognosis. Then TR ratio which is extracted for TR prediction is predicted using the chosen historical data considering the similarity of different data sets. Finally, capacity is estimated sequentially based on the proposed model with the predicted TR and cycle number N. The results show that TR can not only indicate state-of-health more accurately, but also provide more precise and better robustness in RUL prediction and SOH monitoring. Furthermore, the regeneration of battery can be accurately predicted by our method.","PeriodicalId":140911,"journal":{"name":"2016 IEEE International Conference on Prognostics and Health Management (ICPHM)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115203366","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}

Mahalanobis-Taguchi System (MTS) is considered to be an effective non-parametric approach to carry out the health assessment. In this paper, a Laplacian Mahalanobis-Taguchi system (referred as LMTS) analytical model is proposed to establish a nonlinear mapping relationship between the features of sensor information and the ball screw performance. In order to utilize the limited sensor data effectively, LMTS method is only performed on the speed and motor current signals which are available in CNC secondary-develop interface. Because of the complexity of processing high dimensionality nonlinear features, Laplacian Eigenmaps is utilized to reduce the feature data dimension before they were sent to Mahalanobis-Taguchi System as inputs. Compared with the classical dimension reduction methods, the intrinsic low dimensionality manifold by Laplacian Eigenmaps in Mahalanobis feature space characterizes the performance degradation more accurately and robustly. Among many ball screw assessment technologies, this LMTS assessment is a promising data driven based approach because of less influence in the machining process and few changes in the original structural design. The results show that LMTS monitoring may enable the practical application of online real-time assessment for ball screws.","PeriodicalId":140911,"journal":{"name":"2016 IEEE International Conference on Prognostics and Health Management (ICPHM)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115716796","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}

Apart from enhancing maintenance decision support in aspects such as task planning or resource allocation, the data could assist decision makers identify the focal root causes of recurrent equipment failures. In this way, more effective strategies may be formulated and targeted at these focal causes. Despite the increased adoption of maintenance information systems and, as such, availability of maintenance data few techniques so far developed leverage on the maintenance data for decision support in root cause analysis. A particular focus in this regard relates to application of techniques for data mining such as association rule mining. In particular, association rule mining is attractive in the sense of analyzing failure associations embedded in the maintenance data. Thus, this study proposes a methodology for enhancing decision support for root cause analysis in maintenance decision making. The methodology leverages on two association rule mining algorithms - Apriori and Predictive Apriori. Moreover, the methodology incorporates a data standardization step, whereof standard terms and vocabulary are adopted from the ISO 14224 and used for standardizing the equipment failure descriptions. Thereafter, the standardized descriptions are applied as input to an association rule mining framework from which important failure associations are extracted and validated by experts for relevancy. After which, the extracted failure associations are used to generate causal maps, and from the maps, the focal root causes of the equipment failure are identified. The added value of the proposed methodology is demonstrated in the application case of thermal power plant maintenance data.","PeriodicalId":140911,"journal":{"name":"2016 IEEE International Conference on Prognostics and Health Management (ICPHM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126057965","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}

To this end, it is important to be able to perform maintenance before it's needed. By continuously monitoring turbine health, it is possible to detect incipient faults and schedule maintenance as needed, negating the need for unnecessary periodic checks. To date, a strong effort has been applied to developing Condition monitoring systems (CMSs) which rely on retrofitting expensive vibration or oil analysis sensors to the turbine. Instead, by performing complex analysis of existing data from the turbine's Supervisory Control and Data Acquisition (SCADA) system, valuable insights into turbine performance can be obtained at a much lower cost. In this paper, data is obtained from the SCADA system of a turbine in the South-East of Ireland. Fault and alarm data is filtered and analysed in conjunction with the power curve to identify periods of nominal and fault operation. Classification techniques are then applied to recognise fault and fault-free operation by taking into account other SCADA data such as temperature, pitch and rotor data. This is then extended to allow prediction and diagnosis in advance of specific faults. Results are provided which show success in predicting some types of faults.","PeriodicalId":140911,"journal":{"name":"2016 IEEE International Conference on Prognostics and Health Management (ICPHM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131274336","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}

This test method was developed to simulate a situation involving driving an electric vehicle in the city. D2SADT contains two controllable dynamic stress variables: the environmental factor corresponding to temperature cycling and the power factor corresponding to charging-discharging currents and times at which they were implemented simultaneously. A reference power test was performed repeatedly at a certain time (e.g., five temperature cycles), and the cell capacity was then calculated to monitor the degradation of the batteries. A compositional reliability assessment using the gamma process and Monte Carlo simulation was implemented to calculate the likelihood values of the test samples, LiFePO4 batteries, on the basis of their capacity loss. The test results indicate that the battery capacity decreases over time, validating the novel test method (D2SADT). Moreover, the modeling results indicate that the gamma process combined with Monte Carlo simulation provide superior accuracy for predicting the lifetimes of the test batteries compared with the baseline lifetime data (true degradation route and lifetime). Furthermore, the results indicate the high prediction performance of the proposed model because an error rate of within 5% was obtained after half of the cycles were completed (70 temperature cycles), including the measurements.","PeriodicalId":140911,"journal":{"name":"2016 IEEE International Conference on Prognostics and Health Management (ICPHM)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131891512","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 concept of applying OS-ELM to fault detection is demonstrated on an artificial case study. We expect that OS-ELM can contribute to improve the fault detection and also the associated initiation of maintenance activities for engineering components working in an evolving environment such as electric components, bearings, gears, alternators, shafts and pumps, in which the monitored signals are not only significantly affected by working load and surrounding environment but may also experience some modifications due to a slow aging and degradation process.","PeriodicalId":140911,"journal":{"name":"2016 IEEE International Conference on Prognostics and Health Management (ICPHM)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130444187","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}

Using the discretization of the degradation path and the time axis, closed-form approximations for the reliability quantities are obtained using the transition probability matrix. Unlike the conventional method which is applicable only for a small number of degradation states, the calculation of these quantities can be accomplished with just the basic manipulation of the transition matrix, which is computationally efficient and applicable to real-time conditional reliability calculation for a general number of states.

Firstly, an exponential model is adopted to approximately express the degeneration of battery capacity. Secondly, a novel SVR-UPF method is presented to solve the degeneracy phenomenon of the UPF algorithm, and then it is applied to predict the battery RUL. Finally, some experiments and comparisons have been done to validate the improved SVR-UPF prediction method.
