The microcontroller regulates LED light output with pulse-width modulation current and changes the light color with the current ratios of red, green and blue LEDs. While the LED light output varies with temperature, the microcontroller stabilizes the light output of LED with feed-forward compensation and reduces the color deviation in chromaticity diagram. The color deviation is measured with a miniature spectrometer and the calibration of white balance is executed based on the chromaticity coordinates of the used red, green and blue LEDs. Some color points inside the chromaticity diagram and along the blackbody locus are tested to verify the performance of the RGB LED light source. Test results show that an 8-bit microcontroller may effectively regulate the light colors and brightness of a RGB combinational light source. The implemented RGB LED light source can be a good light fixture for mood lighting in somewhere, such as, hotels, restaurants, hospitals, advertisement walls and others.","PeriodicalId":234296,"journal":{"name":"2010 5th IEEE Conference on Industrial Electronics and Applications","volume":"248 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132703142","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}

Firstly, based on the model-set selecting method for multiple model adaptive control, this system preserves the performance of multiple-model approximating nonlinear property of controlled plant at close quarters, therefore the control system is robust. Secondly, fuzzy adaptive weighted control algorithm is proposed to overcome the output disturbance that caused by model switching. The weighted values are obtained by fuzzy decision-making. In this way the corresponding controller can be switched smoothly when the model is selected through switching. Thirdly, because the output predictive value of practical controlled plant is calculated by weighted average of respective sub-models output probabilities, it can rapidly image the variation of plant characteristic. Meanwhile, the output value of controller is optimized by dynamic matrix control algorithm, so the system has better dynamic performance. Furthermore, because of the convenient design and good real-time performance, this algorithm is of great significance and practical engineering value. This algorithm is applied to the main-steam temperature of a supercritical 600MW Once-through boiler; simulation experiments demonstrate the feasibility and good performance of the proposed approach compared to the former approaches.","PeriodicalId":234296,"journal":{"name":"2010 5th IEEE Conference on Industrial Electronics and Applications","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133313159","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 wastewater was treated by aeration and disinfection at last. In order to increase the efficiency, the ash conveying water was used as the cogulating aid in the process. The experimental results showed that the presented process was effective. The quality of the wastewater after treated was stabile and the ash conveying water was beneficial to the flocculation promotion. The effluent was well used for the circulating cooling water system.

This paper presents a power weighted synchronous control method, which is suitable for parallel inverters of different power capabilities. The key concept of the proposed strategy is that the sinusoidal reference signal is decided by the common synchronous pulse signal, which is determined by the majority of the inverters, and the power weighting factor is taken into account. By doing so, the sinusoidal reference signal cannot be interrupted even though one of the modules is fault or dropout. Firstly, the operation principle is described by comparing the conventional method and the proposed method in this paper. Secondly, the hardware implementation is given. Then a detailed reliability failure analysis of synchronous regulation is presented, which shows that higher precision of the control system is obtained compared with the existing methods. At last, the experimental results prove that the control strategy can be well achieved by the designed circuit, and the synchronization of each module is realized.","PeriodicalId":234296,"journal":{"name":"2010 5th IEEE Conference on Industrial Electronics and Applications","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115022231","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}

MPSO takes advantage of multiple sub-swarms with mixed search behavior to maintain the swarm diversity, and introduces cooperative mechanism to prompt the information exchange among sub-swarms. Moreover, MPSO adopts an adaptive reinitializing strategy guided by swarm diversity, which can contribute to the global convergence of the algorithm. Through the mixed local search behavior modes, the cooperative search and the reinitializing strategy guided by swarm diversity, MPSO can maintain appropriate diversity and keep the balance of local search and global search validly.
