This paper introduces an multi-level inverter SHEPWM technique based on Walsh transform, and analyzes the models of multi-level inverter PWM output waveforms. Using the Walsh function waveform analytic technique, the multi-level inverter's switching angles are optimized by solving linear algebraic equations instead of solving nonlinear transcendental equations. By searching all feasible initial conditions, the solutions are the piecewise linear equations with the fundamental amplitude. The problem of on-line solving the multi-level inverter's switching angles is resolved by the piecewise linear equations. Finally, The simulation and experimental results verify the precise, practicality and feasibility of multi-level inverter based on Walsh functions.","PeriodicalId":309894,"journal":{"name":"2008 3rd IEEE Conference on Industrial Electronics and Applications","volume":"37 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134634604","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, in general, we assume ideal condition, no noise and linear mixing model. In this paper, a number of important performance analyses are discussed. It is shown that estimation of the mixing/demixing matrix should not be the main goal, in the noisy and nonlinear case. Instead, it is proposed to compare outcome of ICA algorithms with different proposed performance techniques, derived for known mixing model and extended to real- world data. In this work, the delay variance vector is suggested as the meaningful performance criterion. A simulation study that compare a few well known ICA algorithms and performance techniques applied to noise data are included.

To improve the convergence property of the least mean squares (LMS) adaptive filter, the DFT-LMS and DCT-LMS preprocess the inputs with the fixed orthogonal transforms and power normalization. We derive the asymptotic results for the eigenvalues and eigenvalue distributions of the preprocessed input autocorrelation matrices with DFT-LMS and DCT-LMS for Markov-2 inputs. These results explicitly show the superior decorrelation property of DCT-LMS over that of DFT-LMS, and also provide the upper bounds for the eigenvalue spreads of the finite-length DFT-LMS and DCT-LMS adaptive filters.

Image bag generator, which can transform images into image bags, plays an important role in applying MIL for CBIR according to some researchers' works. In this paper, two new image bag generators named JSEG-bag and Attention-bag were proposed, respectively. JSEG-bag is based on the JSEG image segmentation algorithm and the Attention-bag is based on a saliency-based bottom-up visual attention computational model motivated by visual physiological experimental results. Preliminary experiments showed that the proposed image bag generators can achieve comparable results to some existing bag generators but are more efficient in indexing images.","PeriodicalId":309894,"journal":{"name":"2008 3rd IEEE Conference on Industrial Electronics and Applications","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126116054","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 expected that vehicle-to-vehicle communication systems will play an important role in intelligent transportation systems. MIMO systems employ multiple transmit and multiple receive antennas, combined with the opportunities opened by large vehicle surfaces on which multielement antennas can be placed, makes MIMO techniques very attractive for vehicle-to-vehicle communications. In this paper, we propose an original street model for MIMO vehicle-to-vehicle fading channels, derived from this model, the analysis of statistical properties of transmit and the receive correlation functions is given, and some numerical results for the special case of isotropic scattering are presented.

Moreover, through regulating the terminal voltage of motor, the system made the rising ratio and dropping ratio of the phase currents be approximate so as to keep the amplitude of the total current in the constant. To further suppress the torque ripple, neural network (NN) control algorithm was researched and applied to the system. The controller comprises a back propagation (BP) NN and a radial basis function (RBF) NN. The former is used to adaptively adjust the parameters of the PID controller on-line.

The classical range-free and range-based localization algorithms have respective pros and cons, which cannot gracefully meet the practical requirements, such as the heterogeneity of network and irregular distribution. Thus, the high-accuracy localization algorithm HILS (hybrid iterative least square) is proposed in this paper, utilizing nodes with and without calibration capability. The \"hybrid\" characteristic of HILS holds in two aspects: being able to take advantage of both the range-based information and range-free information, e.g. connectivity and shortest path, and to calculate the initial coarse locations using a certain lightweight algorithm (e.g. DV-Hop) to utilize the error-controllable localization algorithm in heterogeneous networks. Simulation results show that compared with classical range-free algorithm, the proposed algorithm can mitigate the local minima problem in the general iterative algorithms. Although its time consumption is related to the parameter of desired accuracy, it can be reduced by exchanging little amount of information between nodes to rank the order to localize, and by using the optional initial estimation with a certain lightweight range-free algorithm. Experimental analysis represents that HILS is a practical, stable and effective localization algorithm.","PeriodicalId":309894,"journal":{"name":"2008 3rd IEEE Conference on Industrial Electronics and Applications","volume":"237 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121039653","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 method utilizes Lyapunov function candidate to guarantee the convergence and track the speed command of the SynRM system asymptotically.
