The AAIC contains two techniques to improve the quality of decompressed images. The first is a Mean Adaptive Image Coding (MAIC) to reduce the impact of noise on image compression. The second is a Content-based Bit Exchange Technique (CBBET) to provide an adaptive bit distribution which improves the image quality while preserving fixed word length compression feature. Experimental results show that the proposed AAIC outperforms other coding algorithms used in the same type of application.","PeriodicalId":304500,"journal":{"name":"2011 6th IEEE Conference on Industrial Electronics and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121300585","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, we present the performance of an Adaptive Scheduling MAC (AS-MAC) protocol with different Adaptive Scheduling period (AS-period) in multi-hop networks. AS-MAC achieves very good performance in energy-efficiency, end-to-end delay and packet delivery ratio (PDR) in different traffic loads, especially in the scenario of high traffic load. AS-MAC also exhibits adaptability to the different traffic loads with an adjustable AS-period.","PeriodicalId":304500,"journal":{"name":"2011 6th IEEE Conference on Industrial Electronics and Applications","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121424040","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 spherical motor consists of a ball-shaped rotor with a full circle of 8 permanent magnet (PM) poles and a spherical-shell-like stator with two layers of circumferential 24 air-core coils. Based on the torque model of the PMSM, the relationship between current input and torque output can be demonstrated. We design the open-loop controller by decoupling the spinning motion control, which is based on the torque equilibrium theory, from the inclination motion control. Two types of spinning motion control models are proposed and analyzed. The open-loop controller can make the PMSM have the ability to spin continuously and tilt to certain angle. The experiment of open-loop control system based on a personal computer and current controller is designed to validate the control method at last.","PeriodicalId":304500,"journal":{"name":"2011 6th IEEE Conference on Industrial Electronics and Applications","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121621812","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 reduction in number of main switches can also increase the reliability because the control circuits and the auxiliary circuits are thereby reduced to two sets. All main switches in the proposed rectifier operate at zero voltage switching (ZVS) turn-on, while the auxiliary switches operate at zero current switching (ZCS) turn-off. Moreover, the proposed rectifier achieves a near unity power factor, sinusoidal input currents, a regulated output voltage and a bidirectional power flow capability. Finally, a small-signal model is derived and a feed-forward control is presented to achieve almost zero output impedance and zero audio susceptibility. Some experimental results of the proposed soft-switching rectifier, rated 400 W and operated at 40 kHz, are presented for verification.","PeriodicalId":304500,"journal":{"name":"2011 6th IEEE Conference on Industrial Electronics and Applications","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126491682","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}

First, the field-oriented mechanism is applied to formulate the dynamic equation of the PMSM servo drive. Then, an adaptive backstepping approach is proposed to compensate the uncertainties in the motion control system. With the proposed adaptive backstepping control system, the rotor position of the PMSM drive possesses the advantages of good transient control performance and robustness to uncertainties for the tracking of periodic reference trajectories. Moreover, to further increase the robustness of the PMSM drive, a RFNN uncertainty observer is proposed to estimate the required lumped uncertainty in the adaptive backstepping control system. In addition, an on-line parameter training methodology, which is derived using the gradient descent method, is proposed to increase the learning capability of the RFNN. The effectiveness of the proposed control scheme is verified by experimental results.","PeriodicalId":304500,"journal":{"name":"2011 6th IEEE Conference on Industrial Electronics and Applications","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122308889","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}

Experimental results show that the discharging current with a higher frequency or a sharper uprising waveform has less dischargeable capacity.

The cloud controller, with the sliding-mode function as its input, is used to replace the discontinuous switch control part in SMC to alleviate the chattering phenomenon effectively. The design procedure of the proposed controller is described in detail. The Lyapunov stability method is adopted to guarantee the convergence condition. A Genesio chaotic system is used to illustrate the feasibility and effectiveness of the proposed method.

Traditional global histogram equalization usually causes excessive contrast enhancement while local histogram equalization may cause block effect. To overcome these problems, a new method for image contrast enhancement is developed. The novelty is that the weighted average of histogram equalization and exponential transformation are combined and the level of the contrast improvement is adjustable by changing the weighting coefficients. The proposed algorithm not only achieved adjustable contrast enhancement, for color image, it also weakened the situation of lacking color due to the risen of intensity, thus increasing the image saturation. Experimental results show that the proposed algorithm has good performance on enhancing contrast and color for a majority of images mostly taken by the authors.","PeriodicalId":304500,"journal":{"name":"2011 6th IEEE Conference on Industrial Electronics and Applications","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125299450","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}
