Random data packet dropouts in the channels are modeled as independent Bernoulli processes. Quantized signal measurement is handled by a sector-bound method, in which the quantization error is treated as sector-bounded uncertainty. Based on Lyapunov theory, a static feedback controller is obtained in terms of linear matrix inequality (LMI) to ensure the asymptotically stability of the closed-loop system. At last, a numerical simulation example is used to show the validity of the designed controller.","PeriodicalId":232358,"journal":{"name":"2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115196470","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's unable to make appropriate changes according to the actual working condition of the rectifier and the change of working environment, which limits the adaptability of the rectifier to environment and working conditions. Against this point, the single neuron adaptive PID is used as the voltage outer loop controller of the three-phase PWM rectifier instead of the conventional PID. The single neuron could make online adjustment of PID parameters according to the working state of the three-phase PWM rectifier. As a result, it solves the phenomenon that the control performance of the conventional PID controller varies with different working conditions. Through theoretical analysis and simulation verification, the three-phase PWM rectifier controlled by single neuron adaptive PID controller not only own the simple parameter setting process, but strong adaptability, better dynamic and static performance.","PeriodicalId":232358,"journal":{"name":"2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124474596","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}

Therefore, strengthening the judgment of the gear running state in the future and forecasting its developing trend is of great importance. The required data of grey forecasting model is less and the prediction precision is high. Besides the method is simple, we can more accurately describe the inherent law of practical problems. However, it has been found that the actual phenomena tend to be irregular in practice. People usually use the fractional order to replace the integer order. This paper adopts the accumulated generating operation to weaken the original sequence randomness, which makes the disturbances of solutions of grey forecasting model smaller, and fractional order FGM(1,1) model is established to predict the trend of gear fault. The results of GM(1,1) model, Grey Neural Network model and fractional order FGM(1,1) model are compared respectively, and we analyze the differences of fitting precision between the three kinds of models mentioned above. The results illustrate that fractional order FGM(1,1) model has a high prediction capability compared with GM(1,1) model and Grey Neural Network model.","PeriodicalId":232358,"journal":{"name":"2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131610071","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 an important method to scan compensation voltages (CV) at different dispersion voltages (DV) to realize two-dimensional high resolution of FAIMS. Repeat full-spectrum CV scanning consumes a lot of time. In this paper, an intelligent scanning method is proposed to reduce the time of CV scanning by estimating the position of the peak under the adjacent DV condition. Based on spectral position recognition, intelligent partial scanning repeatedly without reducing the effective information of FAIMS spectrum. By employing intelligent scanning method, detection time is reduced to 1/15 of the original full-spectrum scan when the single-peak scan range is set to±2V. This work provides a potential way for quick detection in field detection.","PeriodicalId":232358,"journal":{"name":"2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124659205","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 heterogeneous multi-agent system is composed of first-order and second-order agents, where the second-order agents cannot obtain the velocity information. Firstly, without considering the input saturation, the distributed formation control protocols are designed for multi-agent systems with static leader and active leader respectively. By using Lyapunov stability theory and LaSalle's invariance principle, the protocols are proved to be effective. Then due to the actor saturation, the formation protocols for multi-agent systems with input saturation based on distributed observers and auxiliary systems are presented. Finally, the simulation results are given to illustrate the effectiveness of the proposed protocols.","PeriodicalId":232358,"journal":{"name":"2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116517798","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}
