One way to describe the nonlinear behavior of a process is by use of the nonparametric Volterra Series representation. The drawback of this method lies in the fact that the number of parameters to be estimated increases fast with the number of lags considered for the description of the several impulse responses. The result is that the estimated parameters admit a very large variance leading to a very uncertain description of the nonlinear system. In this paper, inspired from the regularization techniques that have been applied to one-dimensional (1-D) impulse responses for a linear time invariant (LTI) system, we present a method to estimate efficiently finite Volterra kernels. The latter is achieved by constraining the estimated parameters appropriately during the identification step in a way that prior knowledge about the to-be-estimated kernels is reflected on the resulting model. The enormous benefit for the identification of Volterra kernels due to the regularization is illustrated with a numerical example.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"1064 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123163614","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 paper presents an advanced design of a fully integrated active laser target (ALT), which is employed as an optical displacement and orientation sensor. The instrument is mounted on a tunnel boring machine (TBM) and delivers the TBM's pitch and yaw angles to a remote host system. The optical arrangement of the device includes a semitransparent glass target and an opaque aluminum target, whereby measures are taken to increase the sensitivity of red light. A red reference laser beam is projected onto both parallel targets; the positions of the laser spots are observed by two Power over Ethernet (PoE) enabled Gigabit Ethernet (GigE) cameras. A robust plane-to-plane mapping using projective transformation is presented together with a cross validation procedure, which evaluates the quality of the calibration. An a-priori estimation of measurement uncertainty can be given. The system level calibration process yields two sets of transformation coefficients, such that the distortion associated with the optical components and the inexactness of the mechanical construction are effectively canceled out. Multiple images are acquired for a single measurement and analyzed statistically to deliver a statement of measurement uncertainty in order to compensate for mechanical vibrations during the machine's operation.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115110278","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}
