Adaptive tracking controller using BP neural networks for a class of nonlinear systems

Chinese Journal of Systems engineering and Electronics 2004年第4期000卷

An BP neural-network-based adaptive control (NNAC) design method is described whose aim is to control a class of partially unknown nonlinear systems. Making use of the online identification of BP neural networks, the results of the identification could be used into the parameters of the controller. Not only the strong robustness with respect to uncertain dynamics and nonlinearities can be obtained, but also the output tracking error between the plant output and the desired reference output can asymptotically converge to zero by Lyapunov theory in the process of this design *** a simulation example is also presented to evaluate the effectiveness of the design.

By controlling the MOSFET's threshold voltage, power reduction in CMOS VLSIs can be achieved while the operating speed of the circuits is maintained. In this paper, we propose an efficient substrate bias voltage generator with a charge-pumping circuit driven by CMOS inverters for threshold voltage control of MOSFETs. The substrate bias voltage generator can generate negative voltage of -V/sub DD/ level without threshold voltage loss of MOS transistors. The operating characteristics of the generator are also analyzed in detail by using the circuit analysis program H-SPICE.

This paper deals with the fault-tolerant control problem under nonlinear boiler systems with noise and disturbance. MCMBPC (Multivariable Constrained Model-Based Predictive controller) proposed by Wilkinson et al . is used and modified in this paper in order to be applied to nonlinear boiler systems. Fault-tolerant control scheme combining MCMBPC with a fault detection method based on the unknown input observer is proposed. The fault-tolerant controller proposed is shown, via simulation, to have acceptable tracking performance even under some faults of input valves in the boiler system.

AED: A Novel Approach for Intrusion Detection without Abnormal Samples in Big Data Environment

引用

Journal of Data and Information Quality 1000年

作者： Xiaodong Wang Longyun Qi Xingshen Wei Weiping Zhu Haitao Jiang Zhitao Guan School of Control and Computer Engineering North China Electric Power University Beijing China Nanjing NARI Information and Communication Technology Co.

The rapid advance of multimedia devices, including sensors, cameras and mobile phones, has given rise to the prevalence of Internet of Multimedia Things (IoMT), generating huge volumes of application-oriented multimedia data. At the same time, network security issues in the multimedia big data environment also increases. Network intrusion detection (NID) system demonstrates its power in preventing cyber-attacks against multimedia platforms. However, the existing NID methods which are based on machine learning or deep learning classifiers may fail when there is a lack of abnormal traffic samples for training in the real-world scenario. We propose a novel approach for intrusion detection based on deep AutoEncoder and Differential comparison named AED, which only requires the normal traffic samples in the training phase. We conduct extensive experiments on two real-world datasets to evaluate the effectiveness of the proposed AED. The experimental results show that AED can outperform the baseline methods of three categories in terms of accuracy, precision, recall and F1-score.
