| 1 | OSEK/VDX OS服务调用的规范一致性检测方法显示文摘OSEK/VDX(open systems and the corresponding interfaces for automobile electronic/vehicle distributed execu-tive)OS规范描述了一个嵌入式实时操作系统,对系统服务调用的上下文做了严格的限制。违反系统服务调用规范是一种很隐蔽的错误,不会被编译器发现。提出一种OSEK/VDX OS系统服务调用规范一致性的检测方法,利用森林图描述用户自定义代码中的函数及其调用关系,采用矩阵描述OSEK/VDX OS系统服务调用的规则,遍历该森林图的函数调用路径,对于每条路径,结合该规则矩阵判断其规范一致性。实验和分析表明该方法能有效地检测用户自定义代码中隐藏的违反OSEK/VDX OS系统服务调用规范的错误。 | 李银国 叶家盛 蒋建春 | 2010 | 重庆邮电大学学报(自然科学版)2010，22，6： | 5 |
| 2 | Distributed sensor fault diagnosis for a formation system with unknown constant time delays显示文摘In this paper, a distributed velocity sensor fault diagnosis scheme is presented for a formation of a second-order multi-agent system with unknown constant communication time delays. An existing distributed proportion-derivation(DPD) formation control law is adopted and a delay-independent condition is proposed to guarantee the asymptotical formation stability of the formation system based on the Nyquist stability criterion. Then a distributed fault diagnosis scheme is developed. In each agent, a distributed fault detection residual generator(DFDRG) and a bank of distributed fault isolation residual generators(DFIRGs) are designed based on the closed-loop model of the whole system. Each DFIRG is built up on the basis of a reduced-order unknown input observer(UIO) which is robust to the fault of one neighboring agent. According to the robust relationship between DFIRGs and faults, distributed fault isolation can be achieved. Conditions are presented to guarantee that each agent is able to diagnose faults of itself and its neighbors despite the disturbance of time delays. Finally, outdoor experimental results illustrate the effectiveness of the proposed schemes. | Donghua ZHOU Liguo QIN Xiao HE Rui YAN Ruiliang DENG | 2018 | Science China(Information Sciences)2018，61，11： | 5 |

| 4 | Leader-following consensus of second-order nonlinear multi-agent systems subject to disturbances显示文摘In this study, we investigate the leader-following consensus problem of a class of heterogeneous secondorder nonlinear multi-agent systems subject to disturbances. In particular, the nonlinear systems contain uncertainties that can be linearly parameterized. We propose a class of novel distributed control laws, which depends on the relative state of the system and thus can be implemented even when no communication among agents exists. By Barbalat's lemma, we demonstrate that consensus of the second-order nonlinear multi-agent system can be achieved by the proposed distributed control law. The effectiveness of the main result is verified by its application to consensus control of a group of Van der Pol oscillators. | Mao-bin LU Lu LIU | 2019 | Frontiers of Information Technology & Electronic Engineering2019，20，1： | 3 |
| 5 | Integrating Smart Building Energy Data into Smart Grid Applications in the Intelligent Secondary Substations显示文摘Automation has arrived in the low voltage grid domain. In the next few years, the secondary substation—at the barriers of medium and low voltage grids—will thus be upgraded to enable novel functions. In this paper, we present various smart grid applications running on such intelligent secondary substations(iSSN) including their interaction with each other. We integrate energy consumption and production data, as well as forecasts, sensed from the smart buildings' energy management systems(BEMSs) into the operation of the low voltage grid. A suitable framework for those modular applications includes features to initiate their installation, update, removal, the remote operator site, and not requiring staff on-site for such typical reappearing maintenance tasks. | Stephan Cejka Konrad Diwold Albin Frischenschlager Philipp Lehninger | 2018 | Journal of Electronic Science and Technology2018，16，4： | 2 |

This extended result will relax the existenceconditions of the output-based distributed observer for a leader system subject to jointly connected switching communication networks in the literature. As an application of this output-based distributed observer, we solve the cooperative output regulati on problem of a linear multi-age nt system subject to jointly connected switching communicatio n n etworks by composing a purely decentralized control law and the output-based distributed observer based on the certainty equivalence principle. | Tao LIU Jie HUANG | 2019 | Control Theory and Technology2019，17，1： | 2 |

| 9 | Machine learning methods to assist energy system optimization显示文摘(1) Machine learning methods to assist energy system optimization,by A.T.D.Perera,P.U.Wickramasinghe,Vahid M.Nik,Jean-Louis Scartezzini,Pages 191-205 Abstract: This study evaluates the potential of supervised and transfer learning techniques to assist energy system optimization.A surrogate model is developed with the support of a supervised learning technique (by using artificial neural network) in order to bypass computationally intensive Actual Engineering Model (AEM).Eight different neural network architectures are considered in the process of developing the surrogate model.Subsequently,a hybrid optimization algorithm (HOA) is developed combining Surrogate and AEM in order to speed up the optimization process while maintaining the accuracy.Pareto optimization is conducted considering Net Present Value and Grid Integration level as the objective functions.Transfer learning is used to adapt the surrogate model (trained using supervised learning technique) for different scenarios where solar energy potential,wind speed and energy demand are notably different.Results reveal that the surrogate model can reach to Pareto solutions with a higher accuracy when grid interactions are above 10 %(with reasonable differences in the decision space variables).HOA can reach to Pareto solutions (similar to the solutions obtained using AEM) around 17 times faster than AEM.The Surrogate Models developed using Transfer Learning (SMTL) shows a similar capability.SMTL combined with the optimization algorithm can predict Pareto fronts efficiently even when there are significant changes in the initial conditions.Therefore,STML can be used along with the HOA,which reduces the computational time required for energy system optimization by 84 %.Such a significant reduction in computational time enables the approach to be used for energy system optimization at regional or national scale. | A.T.D.Perera P.U.Wickramasinghe Vahid M.Nik Jean-Louis Scartezzini 侯恩哲 | 2019 | 建筑节能2019，47，6： | 1 |

| 11 | Distributed Model Predictive Control for Networked Plant-wide Systems With Neighborhood Cooperation显示文摘For large-scale networked plant-wide systems composed by physically(or geographically) divided subsystems, only limited information is available for local controllers on account of region and communication restrictions. Concerning the optimal control problem of such subsystems, a neighbor-based distributed model predictive control(NDMPC) strategy is presented to improve the global system performance. In this scheme, the performance index of local subsystems and that of its neighbors are minimized together in the determination of the optimal control input, which makes the local control decision also beneficial to its neighboring subsystems and further contributes to improving the convergence and control performance of overall system.The stability of the closed-loop system is proved. Moreover, the parameter designing method for distributed synthesis is provided.Finally, the simulation results illustrate the main characteristics and effectiveness of the proposed control scheme. | Ting Bai Shaoyuan Li Yi Zheng | 2019 | IEEE/CAA Journal of Automatica Sinica2019，6，1： | 1 |
| 12 | Recursive Approximation of Complex Behaviours With IoT-Data Imperfections显示文摘This paper presents an approach to recursively estimate the simplest linear model that approximates the time-varying local behaviors from imperfect(noisy and incomplete) measurements in the internet of things(IoT) based distributed decision-making problems. We first show that the problem of finding the lowest order model for a multi-input single-output system is a cardinality(l0) optimization problem, known to be NP-hard.To solve the problem a simpler approach is proposed which uses the recently developed atomic norm concept and the modified Frank-Wolfe(mFW) algorithm is introduced. Further, the paper computes the minimum data-rate required for computing the models with imperfect measurements. The proposed approach is illustrated on a building heating, ventilation, and air-conditioning(HVAC) control system that aims at optimizing energy consumption in commercial buildings using IoT devices in a distributed manner. The HVAC control application requires recursive thermal dynamical model updates due to frequently changing conditions and non-linear dynamics. We show that the method proposed in this paper can approximate such complex dynamics on single-board computers interfaced to sensors using unreliable communication channels. Real-time experiments on HVAC systems and simulation studies are used to illustrate the proposed method. | Korkut Bekiroglu Seshadhri Srinivasan Ethan Png Rong Su Constantino Lagoa | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，3： | 1 |
| 13 | Impacts of practical channel impairments on the downlink spectral efficiency of large-scale distributed antenna systems显示文摘Channel impairments are major limiting factors in the performance of large-scale antenna systems. In this paper, we analyze the impacts of practical channel impairments caused by pilot contamination,Doppler shift, and phase noise on the downlink spectral efficiency of large-scale distributed antenna systems(L-DASs) with maximum ratio transmission(MRT) and zero-forcing(ZF) beamforming, in which per user power normalization is considered. Using a joint channel model that allows study of the simultaneous impacts of these channel impairments, we derive accurate and tractable closed-form approximations for the ergodic achievable downlink rate, thereby enabling spectral efficiency analysis of L-DASs and an efficient evaluation of the impacts of the channel impairments. It is shown that channel impairments reduce the downlink spectral efficiency and have a significant impact on ZF beamforming. The asymptotic user rate limit is also determined, from which we analyze the asymptotic performance of L-DASs with channel impairments. The analytical results show that MRT and ZF beamforming achieve the same asymptotic performance limit even with channel impairments. It is also found that the use of a large-scale antenna array at the base station sides can weaken the impacts of channel impairments. | Jiamin LI Dongming WANG Pengcheng ZHU Xiaohu YOU | 2019 | Science China(Information Sciences)2019，62，2： | 1 |

| 15 | Iterative Learning Control for Discrete Parabolic Distributed Parameter Systems显示文摘In this paper, iterative learning control(ILC) technique is applied to a class of discrete parabolic distributed parameter systems described by partial difference equations. A P-type learning control law is established for the system. The ILC of discrete parabolic distributed parameter systems is more complex as 3D dynamics in the time, spatial and iterative domains are involved.To overcome this difficulty, discrete Green formula and analogues discrete Gronwall inequality as well as some other basic analytic techniques are utilized. With rigorous analysis, the proposed intelligent control scheme guarantees the convergence of the tracking error. A numerical example is given to illustrate the effectiveness of the proposed method. | Xi-Sheng Dai Sen-Ping Tian Ya-Jun Guo | 2015 | International Journal of Automation and computing2015，12，3： | 0 |

| 17 | LARGE SIGNAL DISCRETE-TIME MODEL FOR PARALLELED BUCK CONVERTERS显示文摘As a number of switch combinations are involved in operation of multi converter system, conventional methods for obtaining discrete time large signal model of these converter systems result in a very complex solution. A simple sampled data technique for modeling distributed dc dc PWM converters system (DCS) was proposed. The resulting model is nonlinear and can be linearized for analysis and design of DCS. These models are also suitable for fast simulation of these networks. As the input and output of dc dc converters are slow varying, suitable model for DCS was obtained in terms of the finite order input/output approximation. | Muhammad Mansoor Khan 吴智铭 | 2002 | Journal of Shanghai Jiaotong university(Science)2002，7，1： | 0 |
