However, it is still difficult for most of them to reach the performance of fast search and optimize the parameters with high quality. Hence, an optimal predicting PID controller based on elite-based hybrid genetic algorithm is presented which improves the simple GA in a large degree with some new strategies and is suitable for the process with unknown time-varying delay, disturbance and time-varying parameters. The simulation results show that the controller has enhanced response speed and robustness. It is an effective control algorithm that combine elite-based hybrid genetic algorithm with predictive control.","PeriodicalId":294566,"journal":{"name":"2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128798921","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}

Home service robots are expected to play an important role to support elderly people at home to improve their life quality. Unlike industrial robots, home service robots face many challenges in terms of safety, autonomy, flexibility and usability, etc. How to efficiently realize human-robot interaction is one of the main areas to achieve home service tasks. Understanding the mechanisms of empathy in human beings and applying such mechanisms to home service robots is crucial to make human-robot interaction natural and friendly. Recent studies shows the links in the functional, and neural mechanisms between imitation and empathy in human beings. In this paper, algorithms are developed to allow robots to understand natural color names given by the user to help locate target objects, and showing by examples is applied to express human's intentions to robots in imitation. Case studies are conducted to demonstrate the proposed approaches.","PeriodicalId":294566,"journal":{"name":"2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128648047","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 existing MCBA algorithm with searching frontiers, however, has a high computational complexity, which depressed the applicability of MCBA. In this paper, we design a fast algorithm of MCBA that examines for the bounded point based on the convex envelopes of the overflow and underflow curve. As a result, our algorithm can work out an MCBA scheme in a shorter time because we can find the bounded point with a linear complexity, and calculate each transmission rate within several iterations. The simulation using real video traces confirmed the philosophy and efficiency of our algorithm.","PeriodicalId":294566,"journal":{"name":"2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009)","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124455858","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 analyzing the two technique principle, by the use of the optimized complex orthogonal wavelet packet and space-time coding technique, we propose a complex orthogonal wavelet packet based MC-CDMA system with space-time coding, and investigate the system bit error rate performance over Rayleigh fading channel. Theoretical analysis and simulation results show that the proposed complex wavelet packet based MC-CDMA (CWP-MC-CDMA) system outperforms conventional MC-CDMA system and it is slightly superior to the conventional MC-CDMA with cyclic prefix (CP). Without any CP, the system has much higher spectrum efficiency. Especially, the application of space-time coding technique significantly improves the system ability to combat channel fading and various interference. Moreover, the space-time coded CWP-MC-CDMA system has comparative superiority to space-time coded MC-CDMA with CP.","PeriodicalId":294566,"journal":{"name":"2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117285716","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}

Since the pilot allocation is solid with the FUSC model, only we can do is to incorporate two OFDM symbols to estimation the channel response, and it can improve the channel estimation performance, but it can’t cancel the error floor exhaustively. So we combine the preamble and pilot carrier to resolve the problem. Here we introduce slope interpolation tracing algorithm that combines preamble and pilot well for consult. Simulation result shows that the proposed algorithm and preamble only scheme can decrease the error floor for SUI_5 channel drastically when the coherent bandwidth of channel is narrow, however they can’t trace the fast Rayleigh fading channel. We also conclude that pilot only scheme exits error floor when the coherent bandwidth of channel is narrow though with better performance for fast Rayleigh fading channels.","PeriodicalId":294566,"journal":{"name":"2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126635394","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}
