By applying MEMS sensor signal processing technology, micro controller-based stepper motor control and electronic image stabilization technology based on grayscale projection, the system has good stability against large angle changes and high-frequency small-amplitude jitter. By combining the Kalman filter in the CamShift framework, the target tracking performance in the similar background is improved.

However, if multiple rectifiers connected to power grid at the same point of common coupling (PCC), it may drive the converters to enter instability region of low-frequency oscillation. This paper studies a low-frequency oscillation phenomenon that is also a Hopf-type bifurcation in grid-connected converters. The instability phenomenon characterized by the oscillation of converters' output voltage, and large amount of harmonics appear on the line current. The input admittance model of converter and output impendence model of non-ideal grid have been established, and transfer matrix function between input current and input voltage of the system is derived. Nyquist stability criterion is adopted to judge the stability of the system. The phenomenon is verified by simulations in MATLAB.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"102 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":"121391980","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}

With high sampling rates and well synchronized data, phasor measurement unit (PMU) has been widely used in dynamic state estimation (DSE). However, the PMU data cannot be used directly by controlling and scheduling due to the stochastic noise. Based on interpolation H∞ extended Kalman filter (IHEKF), in this paper, a novel dynamic state estimation for synchronous machines is proposed. On the basis of the extended Kalman filter (EKF), the proposed method uses the adaptive interpolation method and the H∞ theory to improve the accuracy of estimation and the robustness about measurement noise. Finally, simulation shows that the IHEKF performs well in the estimation accuracy, as well as the robustness about measurement noise, compared with the EKF.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"3 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":"125414819","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}

However, image deblurring has always been a difficult problem in the field of image processing. The traditional methods can effectively improve the image quality by image denoising technology. But this kind of methods has limit ability in recovery clear image from very vague images. Instead of previous methods, we focus on more challenger task that recovery high-resolution image from very vague images. We proposed to use the deep learning way to solve the problem and designed an end-to-end deep neural network for this task. To improve the quality of vague and ensure the accuracy of recovery images, we train our deep neural work by the adversarial training way and design our network based on encoder-decoder network using the convolution layer as network layers.

At first, it designs three typical experimental scenarios of following, overtaking, and target search according to the research goal, selects 12 subjects and does the experiment of distracted driving using the driving simulation platform and the eye tracker. Then, the data is processed and repaired. After the static experiment verification threshold, the difference of the pupil diameter value was treated. The method of sliding standard deviation is used to automatically identify the abnormal mutation of pupil diameter, and use linear interpolation to repair. Finally, by the methods of variance, mean square root and recursive graph, this paper analyzes the changes of pupil diameter in three scenes such as gallop, overtaking and target search, and realizes the recognition of driver's visual distraction. The research results show that the changes of drivers' pupil diameter is more stable and small discrete degree in normal driving condition, on the contrary it is unstable and large discrete degree in distracted driving.

The main challenge in multi-AUV target hunting is the design of AUV's motion path and coordination mechanism. To conduct the cooperative target hunting by multi-AUV in underwater environment, an integrated algorithm based on improved potential field (IPF) is proposed. Firstly, a potential field function is established according to the information of underwater environment. Then, the dispersion degree, the homodromous degree and district-difference degree are introduced to increase the cooperation of the multi-AUV system. Lastly, the target hunting is solved by embeds the three kinds of degree into the potential field function.
