This control protocol is governed by a trigger defined based on an internal dynamic variable. An event-triggered control system with a output-feedback controller is studied. The asymptotic stability of the resulting closed-loop system is guaranteed by a condition in terms of an LMI (Linear Matrix Inequality). By solving this LMI, we can design the event condition. A candidate Lyapunov function is proposed to illustrate the asymptotic convergence of the closed-loop system.

In consideration of the key position of power supply in the device, estimating remaining useful life (RUL) of PEMFC has positive effects in its new stages of development. Currently, RUL estimation of industrial facilities has played an extremely important role in the field of high safety and reliability requirements. For practical systems, the state is often a stochastic process with inevitable degradation during the runtime. In truth, a large amount of data about system operation state is available, and the linear stochastic degradation model is widely applicable to stochastic degradation system. In view of this, this paper selects the proton exchange membrane fuel cell as an object of study, and the remaining useful life is estimated based on its monitoring data. At first, a brief introduction to proton exchange membrane fuel cell is covered. Then, the stochastic degradation model is built and the method of predicting the remaining life is given. At last, the RUL predicted value is obtained and the feasibility of the method is verified by the simulation results with high precision.","PeriodicalId":232358,"journal":{"name":"2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"46 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":"121448247","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}

To solve this optimization problem online efficiently, a particle swarm optimization (PSO) is proposed to search for the global optimal solution as the control input.

This paper, however, presents a BSS method in underdetermined mixing situation for non-sparse signals based on the local mean decomposition (LMD) algorithm. The BSS method firstly introduces LMD into the BSS problem to rebuild a few extra mixing signals. Such signals are then combined with the initial mixtures such that the underdetermined BSS problem is transformed into a determined one and the difficulty of the deficiency of the mixtures is overcome. For the rebuilt mixtures and the newly formed determined BSS problem, two BSS algorithms are proposed to recover the sources. One algorithm uses singular value decomposition on the second-order statistics matrix of the new mixtures to realize the separation, and the other employs an independent component analysis (ICA) type BSS algorithm with stable Frobenius norm constraint on the separating matrix. The simulation results have demonstrated that the proposed underdetermined BSS algorithms can process non-sparse signals, and can acquire a nearly 3dB lower mean square error than the previous non-sparse BSS algorithm.","PeriodicalId":232358,"journal":{"name":"2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"14 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":"116822847","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 the previous literature, the idea of landing control is to use the system output, and error's feedback to control, which takes a large lag in the control, and is difficult to fundamentally improve the landing control accuracy and dynamic performance and so on. In this paper, the preview control of carrier landing is studied, and the preview information of the gliding path and the deck motion is used to guide the aircraft carrier to make the advance operation. Firstly, the landing preview controller is designed, then the robust Hinf filter is designed to predict the deck motion, and the preview information of the deck motion is obtained. Finally, the preview control is carried out under states discrete sampling. Simulation results show that the preview information and control can significantly enhance the aircraft's ability in tracking the glide path and deck motion.","PeriodicalId":232358,"journal":{"name":"2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"98 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":"117222421","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}

Binomial crossover and exponential crossover are two commonly used crossover operators in current popular DE. It is noteworthy that these two operators can only generate a vertex of a hypercube defined by the mutant and target vectors. In this paper, using intermediate recombination to generate an offspring within the hypercube is proposed, named Intermediate Recombination Differential Evolution (IRXDE). In this method, intermediate recombination can make a systematic search in a hypercube defined by the parent solutions. The proposed strategy has been evaluated on a test-suite of 20 benchmark functions. The results of the experiments indicate that IRXDE is competitive with respect to some other DE strategies.","PeriodicalId":232358,"journal":{"name":"2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"17 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":"115210619","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}
