The triac is modeled as a nonlinear equivalent resistor. Considering the triggering and conducting conditions of the triac and the conducting condition of the rectifier, a piecewise state space model is set up. Based on that, a discrete iteration mapping model is further developed to analyze the transient behavior of the system. The typical characteristics of various period-doubling bifurcation phenomena are described by phase portraits. Using the symbolic sequence analysis method, both the border collision and standard period-doubling bifurcations are identified in the system. It has been found that the border collision bifurcation is caused by the missing conduction of the triac. A set of bifurcation diagrams showing the period doubling bifurcation behaviors of the system with relation to the circuit variables and parameters have been plotted. The results obtained can be used to guide the analysis and design of thyristor type controllable rectifier circuits. The analysis method is useful for investigating nonlinear bifurcation behaviors in similar switch-mode circuits.","PeriodicalId":405687,"journal":{"name":"2009 IEEE International Conference on Industrial Technology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126590925","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}

It also gives the principle of the two-probe flatness error separation measurement, establishes the corresponding mathematical models, and carries on the simulation analysis and experiment testifying. Theoretical simulation and experimental result have proved the correctness and effectiveness of the separation principle (1) after analyzing the data with the two-probe error separation measurement, we can obtain the flatness of the panel measured as well as the straight error of the guiding rail.(2) when measuring with the two-probe measurement, the accumulation error of the initial position of the sensors is linear, so it can not influent the assessment of the error.(3) the two-probe error separation technology uses less one or two probes than the flatness error separation technology with the three or four probes does, so it need not consider installing several sensors on a plane and eliminates the problem made by the non-linear accumulation error of the initial position of the sensors. Therefore, the two-probe flatness error separation measurement this paper gives can make the flatness error separation technology more applied.","PeriodicalId":405687,"journal":{"name":"2009 IEEE International Conference on Industrial Technology","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123340365","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}

Due to the combination of mechanics, electronics, and software in the field of mechatronics, specific methods and tools are used in the development process. Nowadays, many solutions exist for describing the specification of production plants. In order to reduce the product and development costs as well as to increase their quality, the development process is strongly supported by models. These models enable an early validation of the required properties. Especially those models applied at the end of the development process or in virtual or hybrid commissioning represent the required behavior of the plant fairly in detail. Therefore, not only increasing attention is drawn to the reduction of efforts for modeling and simulation but to their reuse in similar developments, e.g. by providing construction kits for simulation or their application even in the lifecycle of the production plants. Unfortunately, this kind of reuse, e.g. during the operation phase, is not a focus of current research, although the potential of improving e.g. the operation phase is considerable. In this paper, an approach on how to apply models in the operation phase by synchronous and forward simulation is discussed and an example is presented.","PeriodicalId":405687,"journal":{"name":"2009 IEEE International Conference on Industrial Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121099034","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}

A traditional casting process uses a mold with a pouring gate and some sprue runners through which melted metal is introduced into a mold cavity. In recent years, we have developed a novel casting process that improves the yield of production and reduces heat loss. The new process, called a press casting method, has the capability to produce a thin wall casting. In order to carry out the new casting process, mold shaping that affects the accuracy of goods must always be observed. In this paper, we propose a method for measuring a mold shape using two pairs of stereo cameras. A stereo camera method for 3D shape measurement is widely used in various fields. The reason is that the method can obtain 3D data of a shape of an object within a very short period of time without contact with the object. But search process for finding a stereo pair images takes not a little time, and it is the weakest point of the method. We achieved fast searching by using a shape model of a metal mold to form the sand mold. The experimental results showed that our proposed method is useful to evaluate position and orientation of the cavity of the mold with required accuracy and acceptable time.","PeriodicalId":405687,"journal":{"name":"2009 IEEE International Conference on Industrial Technology","volume":"16 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123660546","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}
