Algebraic Riccati equation based method is used to design a family of state feedback laws for the constrained output regulation problem. In contrast to the existing methods, complete knowledge of the system dynamics is no longer required in this paper. Instead, the data collected from on-line is efficiently utilized to obtain the adaptive optimal control policy. It is shown that the presented method can find feedback control inputs with constraint of amplitude saturation and the ability to stabilize a given linear system with all its poles inside or on the unit circle. Finally, a simulation example is carried out to demonstrate the conclusions of the whole paper.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126061484","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 order to extract the features of the image from multiple angles and provide more abundant information for recognition, a new method of 2DPCA face recognition is proposed. The new algorithm first self-corrects the face image, at the same time, it extracts the low frequency information of the image, and then it uses the Perceptual hash technique to obtain the ‘fingerprint’ of the image. Then, the new algorithm will rotate multi-angle images from the self-corrected face images and extract the features separately to get multi-angle feature information. Finally, the training sample pictures are classified again for each category, and the images of similar expressions or features are classified to retain the special expressions or features. The numerical experiments in the ORL human face databases show that the improved algorithm is superior to the traditional 2DPCA algorithm.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133137598","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 this framework, besides the observer, quantizer and controller are only updated at the event-triggered sampling instants so that it can reduce the computational effort and sampling frequency. Moreover, the condition in terms of linear matrix inequalities is provided to ensure the closed-loop system as well as the observer error system and quantization error system asymptotic stability under the event-triggered strategy.

These will abort missions, crash multicopters, or even injure people. To solve the trap problem and guarantee the mission of each multicopter, an Air Traffic Management (ATM) system should build. In this paper, a local decentralized air traffic protocol for multiple multicopters is proposed to solve the trap problem and complete a series of tasks in a local low altitude airspace. Based on the Artificial Potential Field (APF) method, the protocol is designed in the form of a state machine to coordinate the motions of multiple multicopters.

At first, the nonlinear switched system is represented as Takagi-Sugeno (T-S) fuzzy switched system, i.e., T-S fuzzy models are employed to approximate nonlinear parts. After that, a mode-dependent Luenberger-type observers under synchronous switching is employed to estimate the state of discrete-time T-S fuzzy switched system. By constructing multiply Lyapunov functions (MLFs) and common Lyapunov functions (CLFs), several sufficient conditions are established, in which the actual states of the estimated system under constrained switching (average dwell time (ADT) and mode-dependent average dwell time (MDADT) switching) and arbitrary switching can be tracked by the state of received observers, respectively.

We present the analysis of the interrelation between two processes: one is the spreading of epidemics, the other is the information diffusion which conclude individual sensitivity in multiplex networks. Then we propose a UADU-SIS model of multiplex networks which adopt information diffusion model-UADU and epidemic spreading model-SIS to describe upper and lower layer networks respectively. By using the continuous time Markov process, the analysis reveals the situation of the incidence of the epidemics and allows to capture the evolution of the epidemic threshold. The threshold depends on the topological structure of the multiplex and the interrelation with the awareness process. The research shows that the threshold of Epidemic spreading is not only related to the structure of social network, but also associated with the individual sensitivity and the information diffusion in the communication network.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122647709","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}

Heartbeat Time Series are rich in multiscale information, but the traditional analysis methods only consider them on the single scale, which is not conducive to a comprehensive understanding of the dynamics of the system. Meanwhile, poincaré plot is widely used in the analysis of heart rate variability (HRV) which quantifies the variability of the series, but without probability distribution. To facilitate multiscale visual analysis of RR intervals series, we introduce enhanced EMD multiscale poincaré plot (EEMP). We first employed EMD to create a family of intrinsic mode function (IMF), each of which represents the characteristic time scale embedded in the series. Next, multiscale poincaré plots are constructed for each scale. Finally, to display probability distribution intuitively, color labels are added to each point using kernel density estimation to exhibit the normalized frequency. We illustrated the EEMP approach on RR intervals time series from normal subjects comparing with atrial fibrillation (AF) subjects and congestive heart failure syndrome (CHF) subjects to analyze the dynamics of different physiology states visually. In the future, this generalized approach may be used well in other types of time series.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129242194","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}

Also, a Space vector PWM modulation (SVPWM) based on “120° conduction mode” is utilized for three-phase bridge inverter [2].
