In this paper, a self-learning adaptive dynamic programming (ADP) architecture based reinforcement learning (RL) is proposed to obtain optimal control for UAVs. 1 Compared with the traditional ADP architecture including two networks, one is used to make policy, and the other is used to evaluate policy, We propose to add a third network to replace external reward signals, that is, the agent can acquire reward signals by itself and do not need to interact with the environment. The proposed self-learning ADP method can improve the control performance by online learning while ensuring the state of the system stable at the equilibrium point. Finally, the proposed control algorithm is applied to quadrotor UAVs, and the experimental results show that the effectiveness of the algorithm.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116002603","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}

Image deletion is one of the most important degradation directions when image degradation occurs. The repair process of the digital image repair method is to use the information of the missing part of the image, according to certain repair rules to repair and fill the missing part of the image, so that the repaired image is complete and natural. At present, the existing image inpainting algorithms still have some shortcomings in visual effect and algorithm efficiency. In order to solve the problems of fuzzy details and poor visual perception of the existing technology in the implementation of face image inpainting results, as well as the problem that the whole model could not be controlled due to the mode collapse caused by the use of the generative adversarial network, this paper provides a semantic inpainting method of face image based on multi-scale feature fusion. Using suppression enhancement unit to suppress useless channels, enhance useful channels, acquire long-range and multi-level dependency interaction without increasing parameters, coordinate the details of each position and the details of the far end when repairing the image, expand the receptive field, make up for the lack of information when generating the missing image edge, balance the learning ability of generating network and discriminating network to improve the inpainting effect of missing face image.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116870657","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}

For the nonlinear input problem of the controller, we introduce a continuously differentiable hyperbolic tangent function. We designed a new dynamic signal limited by the controller's input signal and to solve the difficulty of the unmodeled dynamics.

In many recent studies, the adopted models ignore the special electrochemical characteristics of Li-ion batteries, i.e. the correlation between the charging power limit and battery's state of energy and this has led to an inaccurate presentation of the charging and discharging scheduling of the EV fleet. This paper proposes a Li-ion battery charging dynamic model to incorporate this correlation to more accurately approximate the real-life battery charging characteristics. The proposed dynamic model is compared to the static model used in some papers, in which the charging power limit is considered constant regardless of battery state of energy. The differences in cost and time are observed. The result shows in the dynamic model, charging time is longer and the cost is higher than that of in the static model. Increment rate of charging time and cost have been observed in 0.2C (slow charging) and 1C (fast charging) cases for 1000 EVs respectively. These differences can be well attributed to the decreasing charging power limit caused by the increase of SOE.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130560326","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 airport detection and disinfection system is generally not intelligent enough, and the development of passenger health information registration is minimal, which often leads to problems such as missing disinfection and temperature measurement, time-consuming, low efficiency, and difficulty in establishing passenger health information databases. In order to solve such problems and make the airport detection and disinfection system more suitable for the “strict prevention” and “fine control” stages of epidemic prevention and control, this paper designs and develops an airport automatic detection and disinfection channel with the function of recording passengers' health information. STM32 processor, MLX90614 non-contact temperature measurement module, DY-SV5W intelligent voice module, TFT LCD module, infrared switch module, information registration module, camera module, etc. are mounted on the existing ultrasonic atomization disinfection system. At the same time, considering that the radiation from the background environment will interfere with the measurement results and cause certain errors, this paper selects a BP neural network algorithm, which has high fault tolerance and strong generalization ability to compensate the ambient temperature to improve the accuracy of temperature measurement. Through the combination of system software and hardware circuits, a series of functions such as information registration, guiding passengers in and out, infrared temperature measurement, and quarantine disinfection can be realized. Passengers with suspected infection due to abnormal body temperature can be separately identified to ensure the health of people entering and leaving and ease the manual inspection of airport quarantine personnel, disinfection, registration pressure. The function of the system tends to be more perfect, more intelligent and humanized.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130754220","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}

Rather than the current consensus algorithms for multi-vehicle systems with just scalar inertias, we allow the inertias to be matrices. What's more, the inertia matrices are assumed to be heterogeneous as well as unavailable. In particular, a fully distributed consensus algorithm is proposed such that global information is unnecessary for the achievement of the consensus objective. Moreover, a novel adaptive strategy is designed to address the dilemma arising from the heterogeneity and unavailability of the inertia matrices. It is demonstrated that, under the strongly connected graph condition, the designed distributed algorithm ensures the asymptotic convergence of the required consensus objective. The efficacy of the developed distributed algorithm is finally validated by numerical simulations.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"35 22","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132836432","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}

This system first makes a fast but rough compensation to reduce the impact of environmental magnetic field to a very low level, then accurately but slowly compensates the residual magnetic field. The rough compensation is made under low power detection light to achieve high efficiency, while the accurate one is made under high power detection light to achieve high accuracy, which are both automatically performed. This is definitely an advantage over the most existing magnetic compensation systems for the SERF atomic comagnetometer, which rely only on manual adjustments with low accuracy and poor repeatability. The simulation illustrates the good efficiency, accuracy and repeatability of the proposed automatic magnetic compensation system.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132085624","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 meet the high requirements of communication for reliability and real-timeliness, WirelessHART has adopted graph routing to allow retransmission from backup paths when necessary and time slotted channel hopping (TSCH) mechanism to improve reliability by leveraging channel diversity. In this paper, we formulate the problem of maximizing the transmission reliability of multiple flows in a multi-hop WirelessHART network. Considering the path diversity of graph routing, we analyze the characteristics of links that pass through different paths of the same flow. Based on this analysis, We propose an aggregation-based routing algorithm along with a hop-wise scheduling algorithm to solve the optimization problem.
