There are many advantages of the new sensor, such as large operating range, small size, high linearity, and low cost. In this sensor, the input nanometer scale displacement will be amplified by flexure hinges with a multi-stage enlarger configuration. Then the expanded displacement is transferred into an elastic body in which strain gauges are used to convert the deformation into electrical signal. However, after the mechanical amplification, the output electrical signal is still very weak. The effective signal is about 800 nanovolts when the original displacement changes 10 nanometers. Whether the weak electrical signal can be measured effectively will determine the final resolution and accuracy of the sensor. Since the conventional data acquisition method is not suitable in this situation, we design a data acquisition system including hardware and software implementation to measure the weak signal effectively and display the real-time data in upper PC. To test the effectiveness of the whole system, we present a series of comparison experiments. From these experiments, we can get the conclusion that the sensor we proposed has achieved the nanometer scale resolution.","PeriodicalId":351518,"journal":{"name":"2011 IEEE International Conference on Automation and Logistics (ICAL)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122664201","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 study presents the impact of new design aspects of automated storage/retrieval systems with special emphasis on travel time models. In the aim to find energy saving solutions as well as to improve the efficiency rate of AS/RS's, a new design of AS/RS's has been developed using a parallel wire-based Stewart-Gough platform (parallel wire robot) to serve as storage and retrieval (S/R) machine instead of the conventional S/R machine. This innovated system is named Stewart-Gough Platform based Automated Storage and Retrieval System (SGP-AS/RS's). In this study, the impact of the new AS/RS's design on cycle travel time will be investigated by determining the expected travel time for single command. A numerical case study for the travel time analysis based on mini-load storage and retrieval system has been presented. The results illustrate significant reductions in SGP's travel times in automated warehousing systems in comparison with the conventional S/R machine.","PeriodicalId":351518,"journal":{"name":"2011 IEEE International Conference on Automation and Logistics (ICAL)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134097641","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 ship is exposed to the wind, currents and waves in the ocean. In order to counteract these disturbances, the dynamic positioning ship uses solely active propulsion. Since the first-order wave force is too large for the ship's thrust system to deal with and it only causes the high-frequency motion, which do not induce the finial position drift. A filtering algorithm is needed to separate the high frequency motions from the low frequency ones. In this paper the Unscented Kalman Filter (UKF) method is used for the wave filtering of dynamic positioning ships. Noisy position and heading measurements are used by the UKF to estimate the low-frequency motion and the high-frequency motion. A nonlinear platform supply vessel (PSV) model is employed for both the model simulation and the estimator design. An approximation method for the first and second order wave force calculation is used to produce the high frequency and low frequency ship motion. With considering of the wind, currents and waves, some illustrative results of the UKF based wave filtering algorithm are presented.","PeriodicalId":351518,"journal":{"name":"2011 IEEE International Conference on Automation and Logistics (ICAL)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131249035","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}
