We modified the surface of NiTi plate samples by depositing TiO2 oxide using atomic layer deposition (ALD). We found excellent corrosion properties of the coated NiTi samples, implying that ALD has great potential in depositing protection or biocompatible layer for 3D printing. Additionally, using a mechanical tester installed in the sample chamber of a scanning electron microscope, we were not able to see any tensile-load-induced microcracks in the thin atomic layer deposited TiO2 coating. Whereas the TiO2 layers grown thermally by oxidizing NiTi at temperature around 450 °C contained densely distributed microcracks during loading.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115799491","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}

However most existing control methods for this goal require either online force sensing or the exact parameters of the robot, which is usually difficult and expensive. In this paper, two mobile manipulators are utilised to verify a simple cooperative manipulation control scheme. The mobile platforms track offline designed trajectories in order to maintain a formation, while the robotic arms holding a rigid object on top convey compliant behaviours so that the internal force likely to be caused by the motion error of the platforms is suppressed. The dual-arm control is in a Leader-Follower structure and the compliance feature is achieved with a classic PD controller with gravity compensation, easy to implement in industrial application. The effectiveness of the control system is exhibited in experiments.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"58 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134408750","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 is particularly important for electric motors operating in offshore conditions, since they work in hostile environment which often damages data acquisition systems. Therefore, this paper deals with verification and validation of the extended Kalman filter (EKF) for sensorless indirect field-oriented control (IFOC) of an induction motor operating in offshore conditions. The EKF is employed to identify the speed of the induction motor based on the measured stator currents and voltages. The estimated speed is used in the motor speed control mode instead of a physical encoder signal. In addition, we utilize a stationary frame model of the induction machine to assess the fidelity level of the EKF-based estimation of rotor fluxes. The experimental setup is used to validate accuracy of the EKF-based state estimation and motor speed control. The importance of the current work is demonstrated on an example of a full-scale offshore drilling equipment. Real-world speed and load profiles sustained by the gripper arm of the vertical pipe racking machine are scaled down and reproduced by the experimental setup. The proposed EKF algorithm accurately estimates both speed and electromagnetic torque experienced by the reference full-scale electric drivetrain, creating a potential to reduce the number of data acquisition devices in similar type of equipment.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121280768","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 is known that classical image based visual servo control scheme has some problems, e.g., image space singularities and local minima. To tackle this issue this study applied a virtual composite camera model and a 3D visual Cartesian space to calculate the full-rank image Jacobian for visual tracking control. The advantage of this approach is that the image Jacobian obtained will be always non-singular for robustness. This research employed a distributed embedded system including two DSP boards to implement the above visual servo algorithm. The experimental results demonstrate that the proposed visual servo system is feasible in an embedded system.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116979684","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}

Finally, the IPMSM drive system can be automatically operated at the maximum torque/ampere control without requiring any motor parameters. A digital signal processor, made by Texas Instruments Company type TMS-320LF-2812, is used as the computation center to execute the whole control algorithms.

In this work, we present a neural network based approach to reduce the training time while maintain the high recognition rate. The main idea is to perform a preprocessing stage to partition the training data prior to the training stage. A multi-stage approach is then used to deal with various types of input source. Our experiments on real image datasets have demonstrated that the balance between the training time and recognition time can be achieved using the proposed method.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116695960","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}

By connecting a sufficiently large number of used batteries in series, the combined output voltage becomes operable, allowing for further drainage of the residual energy from these batteries. In this study, the discharge behaviors of primary alkaline batteries were characterized. The experimental results showed that batteries connected in series discharged non-uniformly. A \"weakest-link\" phenomenon was observed in that one battery discharged faster than others until it rendered the entire battery bank inoperable. This unconventional voltage supply required additional circuitries for regulation and/or protection to handle the relatively wide range of output voltage. Nevertheless, the concept of draining the residual energy by stacking up multiple used batteries is feasible. The method prolongs the service life of primary batteries and should lead to applications that benefit economy as well as environment. The potential extensions to this method are also discussed.","PeriodicalId":116715,"journal":{"name":"2016 IEEE International Conference on Industrial Technology (ICIT)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115065965","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}
