Inspired by the idea of genetic algorithm (GA), a new two-swarm based PSO algorithm (TSPSO) with roulette wheel selection is proposed. With different parameter settings, the two swarms have different flying trajectory, explore solution space as possible as they can, and enhance the global exploration ability. Roulette-wheel-selection based stochastic selection scheme make particles searching in the neighborhood of better feasible solution intensively and enhances the local exploitation ability. The proposed algorithm is tested on three benchmark test functions. The results show that the proposed algorithm is superior to PSO and GA in the solution of complex optimization problems","PeriodicalId":375135,"journal":{"name":"2006 6th World Congress on Intelligent Control and Automation","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126863932","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}

Then on the basis of the reduction, a multi-neural network based target differentiation algorithm is designed on the fact that the effective combination of multiple neural networks can increase the ability to pattern classification and generalization of the whole system. Parallel network architecture is adopted locally to increase the differentiation accuracy. And the average weighed strategy is applied to fuse the outputs of the parallel neural network classifiers to improve the robustness of the differentiation system to noise, physically plausible failure and missing sonar data situation. The simulation experiments prove that the new method combining with the traditional target differentiation algorithm can increase the accuracy of sonar-based target differentiation for mobile robot in indoor environments","PeriodicalId":375135,"journal":{"name":"2006 6th World Congress on Intelligent Control and Automation","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115019089","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}

On the basis of conventional PI regulator, a fuzzy speed PI regulator was designed according to speed error and its rate of change, which could adjust the proportional coefficient kp and integral coefficient kp dynamically to adapt the system to the speed variations, and advanced the self-adaptation of speed. In voltage vector fuzzy controller model, the stator flux angle, the stator flux error, and the torque error are reasonably fuzzified into several fuzzy subsets to optimize selection of the voltage vector and decrease the torque ripple. The experimental results show that the proposed fuzzy control system not only can ensure swift speed response, small overshooting, and high steady speed precision, but also can effectively decrease torque ripple in low speed.

In this paper, an integration mission model of both periodical mission and non-periodical mission is built based on the characteristic of small satellite mission and a fault-tolerant scheduling algorithm of static scheduling and dynamic adjustment for small satellite is presented combined with mission allocate algorithm and partial dynamic scheduling algorithm of embedded processor. This algorithm combines both the technique of primary/backup copies and the Hopfield algorithm and sum up static assignment to planning and operation problem held in resource and time. Neural network algorithm is used in partial dynamic adjustment of non-periodical mission and backup mission copies that assures the reliability and temporal effectiveness of mission execution. Simulation results show that it achieves higher schedulability compared to some other methods.
