In this paper, we focus on the stochastic finite-time passive control problem for interval energy-storing electrical systems with time-delay and Markov switching. The mathematical model of energy-storing electrical circuit is given firstly, in which not only the error of resistor R, inductance L and capacitor C, but the stochastic disturbance as well are considered. To investigate the finite-time passive control for the interval energy-storing electrical circuit, mathematical model is transformed into a kind of stochastic uncertain systems with time-delay and Markov switching. By constructing a Lyapunov-Krasovskii functional, together with linear matrix inequalities (LMIs) toolbox, some sufficient conditions are given. Meanwhile, the passive controllers are also designed by solving the corresponding LMIs. Naturally, a numerical examples with simulation is given to illustrate the correctness and effectiveness of the designed controller.

This paper addresses the problem of non-fragile H∞ filter design for two-dimensional systems. This filter has interval-type gain variation, which means that it cannot be fully performed. Firstly, by Finslers'lemma, the nonfragile filter design has been formulated as a robust convex optimization problem, which is solved by the classic vertex algorithm. It should be noticed that, for high dimensional systems, the number of LMIS involved is so large that it may be over the processing capacity of Matlab LMI Toolbox. To solve this difficulty, an efficient randomized algorithm is proposed. This algorithm can reduce the number of LMI conditions significantly. Finally, a numerical example is given to illustrate the effectiveness of the proposed method.
研究二维系统的非脆弱H∞滤波器设计问题。该滤波器具有区间型增益变化,这意味着它不能完全执行。首先,利用Finslers引理,将非脆弱滤波器设计化为一个鲁棒凸优化问题,并用经典顶点算法求解。需要注意的是,对于高维系统,所涉及的LMIS数量非常大,可能超过Matlab LMI工具箱的处理能力。为了解决这一难题,提出了一种高效的随机化算法。该算法可以显著减少LMI条件的数量。最后通过一个算例说明了所提方法的有效性。

In this paper, an interesting Hybrid Stochastic Timed Petri Net (HSTPN) is introduced synthetically for a class of hybrid systems with discrete, continuous, conflicting, time-delay and stochastic characteristics simultaneously. Each tuple of the model is performed in detail, the dynamic performance and reachability are analyzed. The proposed HSTPN outperforms conventional hybrid Petri net models in terms of describing the scalability and description capability to hybrid characteristics of hybrid systems. Taking the automatic sorting hybrid system as an example, through analyzing the complexity in modeling, we show how the HSTPN could be adopted to the automatic sorting hybrid system and finally the rationality and effectiveness of HSTPN model are verified.

The host will directly drive electromagnetic equipment to play the lock tongue if the password is correct. The whole process of verifying the unlock password must be done within the scope of authorization time, generally half a day or a day, which is determined by the bank unit. That is to say, such a practice must be carried out within the control of management system. The lock is verified by actual operation in the bank that it can effectively improve the security of Bank ATM safe electronic password system, and it has a profound historical significance to promote the development of bank ATM safe electronic combination lock industry.
针对目前金融行业使用的机械锁已不能满足银行安全可靠的需求,结合辽宁大学巨龙集团提出的产品解决方案,设计了满足巨龙公司要求的新型ATM安全锁系统。该新型ATM安全锁系统由电子密码锁主机、手持式成套智能钥匙和上位机管理中心三部分组成。下位机由Cortex-M3系列MB9AFB44L处理器模块、指纹识别模块和2.4G无线模块组成。银行加钱人员由上位机综合管理系统授权操作授权,通过手持式指纹识别模块验证后,发送信号通知手持式MCU在授权时间内发送数据包,数据包也通过2.4G无线模块传入密码锁主机。当收到数据包时,密码锁主机会提前比较提取,并首先验证手持设备的ID号。如果ID符合权限范围,将提取数据包内容,此时记录数据包内容中的解锁密码和授权记录时间,与密码锁主机生成的密码进行匹配。如果密码正确,主机将直接驱动电磁设备播放锁舌。验证解锁密码的整个过程必须在授权时间范围内完成,一般为半天或一天,由银行单位决定。也就是说,这种做法必须在管理系统的控制范围内进行。该锁经银行实际运行验证,能有效提高银行ATM安全电子密码系统的安全性,对推动银行ATM安全电子密码锁行业的发展具有深远的历史意义。

Pub Date : 2018-06-01 DOI: 10.1109/CCDC.2018.8407813

With the development of modern industry and computer technology, deep learning is widely used in the field of fault diagnosis, but it still faces many challenges, such as data missing due to different sampling rate of different sensor or other data packet of dropout of control system network. Observation data with missing values will seriously affect the result of fault diagnosis. Imputation methods such as regression imputation method intend to solve the problem of data missing to a certain extent. However, as the missing rate increases and the cross-correlation coefficient between observation variable-decreases, the traditional imputation method will fail in extracting the potential feature involved in the missing data. In this paper, a neural network imputation method is proposed to estimate the missed observation. Once online observation data with missing value is available, neural network imputation method is first used to get a structural complete observation sample. Then DNN trained by structural complete data can be effectively classify different fault with high accuracy. Experiment analysis shows the efficiency of the proposed method.
随着现代工业和计算机技术的发展,深度学习在故障诊断领域得到了广泛的应用,但它仍然面临着许多挑战,如不同传感器的采样率不同或控制系统网络的其他数据包丢失等。观测数据缺失会严重影响故障诊断的结果。回归归算等归算方法在一定程度上解决了数据缺失的问题。然而,随着缺失率的增加和观测变量间互相关系数的减小,传统的插值方法将无法提取缺失数据中涉及的潜在特征。本文提出了一种神经网络估计方法来估计缺失观测值。一旦有缺失值的在线观测数据,首先采用神经网络插值方法得到结构完整的观测样本。利用结构完备数据训练的深度神经网络可以有效地对不同的故障进行分类,并具有较高的准确率。实验分析表明了该方法的有效性。

Seru production system (SPS) is now widely adopted in Japanese manufacturing firms to deal with the dynamic uncertain demand. Multi-skilled workers and compact layout make SPS takes the advantage of both efficiency and flexibility. In this paper, we compared the fulfill rate of three skill levels of SPS (single-skilled, long chain two-skilled and full-skilled). The purpose of this paper is to testify which skill level performs best for implementing SPS under fluctuated demand. On this basis, we consider the efficiency decline factor (EDF) which represents the processing time of a worker will be longer when he serves more product types. Scenario decomposition method is adopted to estimate the fulfill rate of three skill-leveled SPS. Numerical experiments show that fulfill rate of long chain two-skilled SPS is almost the same as full-skilled SPS, while single-skilled SPS' fulfill rate decline significantly with the growing of demand fluctuation. Moreover, with considering of EDF, long chain two-skilled SPS performs the best among them.

A new nonlinear composite adaptive control based on immersion and invariance theory is presented for a class of high-order system with parametric uncertainty. The main feature of this control scheme lies in the construction of the adaptive law, which is driven by both tracking error and prediction error. The tracking-error based adaptation law is first constructed using immersion and invariance theory, then the prediction-error based adaptation law is added to it, thus makes a composite adaptive control law. The combination is applied to the immersion and invariance based adaptive control with improved performance. Stability analysis is presented using Lyapunov theory, which shows asymptotical convergence of the tracking error to zero. The validity of the proposed control scheme is illustrated through numerical simulations.

The validity of the proposed control scheme is illustrated through numerical simulations.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132915417","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}

A distributed event-triggered control scheme for first-order discrete-time multi-agent systems over fixed directed network is designed, in order to save energy resources and network bandwidth by reducing communication between agents. Each agent only communicates with its neighboring agents at some specific conditions which are called triggering time instants. The control protocol is designed to achieve the consensus of multi-agent systems, and then the convergence of the algorithm is proved by the Lyapunov method if the network has a spanning tree. Based on the analysis, there is a simulation example at last to demonstrate the effectiveness of the theoretical control protocol.
设计了一阶离散多智能体系统在固定有向网络上的分布式事件触发控制方案,通过减少智能体之间的通信来节约能源和网络带宽。每个智能体只在某些特定的条件下与相邻智能体通信,这些条件称为触发时间瞬间。设计了控制协议以实现多智能体系统的一致性,然后用Lyapunov方法证明了该算法在网络具有生成树的情况下的收敛性。在此基础上,通过仿真实例验证了理论控制协议的有效性。
