Current research has been oriented to provide quantitative assessment of physical activity with ambulatory monitoring approaches. This study presented the design of algorithm integrated with a portable microprocessor-based accelerometry measuring device to implement real-time physical activity identification. This algorithm processes real-time tri-axial acceleration signals produced by human movement to identify targeted still postures, postural transitions or walking. Fall detection is also featured in this algorithm to meet the increasing needs for elderly care. High identification accuracy was obtained during the preliminary test phase and the observed limitations regarding real-time processing was also discussed. The result reveals that this developed algorithm is technically viable for real-time identification in ambulatory monitoring to provide sufficient information in evaluating a person's activity of daily living (ADL) and the status of physical mobility. Possible system integration and applications in the future were also discussed.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126431684","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 discovered that the peak current protecting value increases as the duty cycle decreases. As a result, the safety operation of the switches is damaged greatly. A novel solution to improve over-current protection with constant peak current limitation is proposed by inducing synchronous slope compensation into the current limit function instead of the original constant voltage. The design principle and method of the protection circuit based on a UC3846 PWM controller for the interleaved dual-forward converter is presented. Experimental results are given to verify the analysis.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126202020","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 mechatronic system structure driven by two DC motors is described, and its mathematical modeling incorporating the friction between the wheels and motion surface is derived. By decomposing the overall system into two subsystems: rotation and inverted pendulum, we design two adaptive radial-basis-function (RBF) neural network (DOF) controllers to achieve self- balancing and rotation control. Experimental results indicate that the proposed controllers are capable of providing appropriate control actions to steer the vehicle in desired manners.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128099597","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}

In this mechanism, we inserted an elastic plate, which we refer to as a compliance adjuster plate (CAP), between the joint part and the link. Elastic deformation of the CAP enables the robot to generate compliant arm motion in reaction to external force. The compliance can be easily adjusted according to the requirements of given tasks by controlling the posture of the CAP in regard to the link. Furthermore, the strain observed on the CAP can be used to estimate the actual position of the arm-tip which is moved by an external force caused by contact with the environment. We examined the fundamental characteristics and performance of this mechanism through a comparison of theoretical analysis and the results of several experiments.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121604316","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}

As the main advantage, the Walsh function based algorithm provides a convenient calculating process and simplifies the multiplication procedure in order to obtain reactive component from entire instant power signal. The advantages of the proposed method for the measuring of the reactive power have been verified by experimental studies. One of these advantages is that in contrast to the known existing methods which involve time delay or shifting of the input signal, the proposed method does not require the time delay of the current signal to the pi/2 with respect to the voltage signal. To test the validity and effectiveness of the suggested method for evaluation of the active and the reactive components of the electrical power a simulation tool have been developed using \"Matlab\".","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132538977","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 strategy is based on a discrete-time Luenberger observer combined with a low cost and fast positioning system. The positioning system delivers the coordinates, roll and pitch angles of robot. The discrete-time Luenberger observer is used to estimate all the velocities. A local stabilizer is designed as if all states were measurable. It is shown that the observer and the stabilizer satisfy a kind of separation principle, in the sense that local stability of the closed loop system is preserved when the actual states are replaced by their estimates. Real-time experiments show the performance of the proposed scheme.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133927842","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 proposed MLM offers numerous advantages. First, it can accomplish the levitation force and propulsive force by using only a single power source. Second, with the circular structure, it can provide unlimited traveling distance without the end effect for general characteristics analyses. Third, the stabilization is improved by taking additional mechanical design consideration without using extra set of electromagnet and complicated control. Eventually, a special test facility is designed and implemented for torque test, and the experimental measurements are provided to demonstrate the feasibility of constructing a MLM. Experimental results show that the electrical characteristics of the proposed MLM agree with the theoretical results of a linear induction motor. The measured results can be used to develop a robust controller for the MLM in the future.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130825459","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}

In this paper, a method based on the adaptive linear combiner (Adaline) is presented for harmonic components identification. The convergence speed and the estimation error of the Adaline are governed by the learning parameter (LP) in the weight adaptation rule of this artificial neural network. Thus, instead of a constant LP utilized in the conventional Adaline, this paper proposes the implementation of a fuzzy inference system (FIS) for suitable adjustment of the LP. Two simulation studies are conducted on the MATLAB and PSCAD/EMTDC to show the validity and performance of the proposed method.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132824585","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 synthesized controller achieves simultaneous current control and regulation of the dc-link voltage, allowing extra functionality for the shunt APF as an active rectifier. The designed controller has good tracking performance and can cure the detrimental effects of the inevitable modeling errors and disturbances. Furthermore, a feedforward control loop is implemented to improve the transient response by compensating the dc-load current variations.
