In this work a simulation platform for uninhabited marine and aerial vehicles is proposed. This platform is based in the MDA (Model Driven architecture) approach and the DEVS (Discrete Event System Specification) formalism. Platform independent models (PIM) are used to describe the vehicles and its interaction;then, theses models are traduced to platform-specific models (PSMs) in Matlab-Simulink, Java and other languages. DEVS formalism is designed to describe discrete events model, so in order to use continuous time models the second order quantified states simulation (QSS2) is proposed. This method is applied to an autonomous radio controlled hovercraft and its low level tracking controller. Copyright © 2007 IFAC.

The requirement of Device-to-device (D2D) communication is increasing day-by-day for rapid data transmission by bypassing the base station. Communication can be established either through cooperative devices or non-cooperative devices. Cooperative devices relay the information to the weak user, but the non-cooperative behavior of some intermediate nodes leads to malicious activities like fraud, misguide, and data-threat. In non-cooperative communication, the source node directly transmits data to the destination node (with a direct link) to eliminate the intermediate nodes for higher trust. But, such communications are vulnerable to various security and privacy threats such as spoofing, data modification, etc. due to the long-distance coverage of signal from source to destination. To overcome these security issues, this paper proposes a blockchain-based trusted network for non-cooperative D2D communication in a heterogeneous network, FaitH. Here, the devices are communicating via a secured blockchain network, where all the involved peer devices validate each transmission of data. Blockchain records each activity performed by any D2D node in communication. It helps to detect the malicious behavior of any D2D user. Each device is connected to a smart contract having some predefined rules. FaitH ensures secure, trusted, and reliable communication over traditional systems. © 2021 IEEE.

Injecting auxiliary random noise is an effective approach to implementing the online secondary-path modeling (SPM) subsystem in active noise control (ANC). In this paper, a typical FIR-based narrowband ANC (NANC) system with online SPM is proposed to reduce the sinusoidal noise generated by rotating machines, especially its lower frequency portion. A first-order FIR filter or magnitude/phase adjuster (MPA) serves as a sub-controller in each frequency channel. The contributions of this work are twofold. A bandpass filter bank based on IIR notch filters is introduced to mitigate the coupling between the controller (MPAs) and the SPM subsystem, which significantly improves the performance of the overall system. Furthermore, the proposed system requires only one x-filtering block regardless of the number of targeted frequencies, which considerably reduces the computational cost of the system. Simulations as well as application to real noise are conducted to demonstrate that the proposed system is superior to its conventional version in terms of overall system convergence and online SPM quality. © 25th International Congress on Sound and Vibration 2018, ICSV 2018: Hiroshima Calling.

UPB Scientific Bulletin, Series C: Electrical Engineering 2008年第3期70卷 87-100页

作者： Lupu, Ciprian Petrescu, Catalin Ticlea, Alexandru Dimon, Catalin Udrea, Andreea Irimia, Bogdan Dept. of Automatic Control and Computer Science University Politehnica of Bucharest Bucharest Romania

Structures with inverse model represent one of the successful solutions for the real-time control of the nonlinear processes. The use of these structures imposes solving some specific problems, like determination of static characteristic of the process, construction of inverse model or robust control law design. The paper proposes a structure and the correspondent original methodology of designing and physically implementation based on inverse model command. The applicability of the structure is proved using a real-time structure with an RST control algorithm. In the end, its software implementation and the obtained results are also shown.

There is a significant increase of cloud and networking-enabled applications, leading to an exponential growth of network traffic. Monitoring all these applications and their generated traffic is a challenging and complex task, especially in regard to anonymous networks used to access the Dark Web or darknet. Manual investigation of the network traffic to determine patterns of malicious activity is a very difficult task and the results might not be satisfactory. The usage of machine learning is the most viable approach for the classification of the traffic as normal or malign activity. This paper analyzes CIC-Darknet 2020 dataset to classify the benign and darknet traffic. Before applying any classifiers to our dataset, we have balanced it using Synthetic Minority Oversampling Technique (SMOTE). We have applied PCA to reduce dimensionality, furthermore, ensemble techniques, logistic classifiers, tree-classifiers, and Naive Bayes have been compared and evaluated thoroughly with various evaluation metrics Accuracy, Precision, Recall, F1-Score, and Mathew's Correlation Coefficient (MCC). © 2021 IEEE.

In this paper, we deal with the issue of robust delay-independent asymptotic stability and robust disturbance attenuation problem for linear parameter-dependent systems. Using Hamiltonian-Jacoby-Isaac approach, a parameter-dependent LMI optimization is obtained. It is shown that by utilizing polynomial parameter-dependent quadratic Lyapunov functions, a parameter-dependent LMI optimization problem is derived. Therefore, state feedback control is determined by solving a parameter-independent LMI. Finally, the applicability of the proposed design is illustrated on a simple example. © 2005 IEEE.

A novel nonlinear controller that inherently limits the RMS value of a three-phase grid-following inverter current is presented in this paper. Using the dynamic model of the inverter in the rotating dq reference frame, a nonlinear control scheme is formulated to ensure accurate real and reactive power regulation with RMS current limitation that avoids the use of saturation units with upper/lower limit adaptation, as commonly used in the existing approaches. In particular, it is analytically proven by using fundamental nonlinear systems theory, that the RMS value of the inverter current will never violate a given maximum value, both during the transient response and at the steady-state. Moreover, a detailed root locus analysis is provided to guarantee the asymptotic stability of the desired equilibrium point for the closed-loop system. Finally, to validate the proposed controller performance, simulation results of a grid-following three-phase inverter equipped with the proposed control approach are presented under both normal and unrealistic values of the real and reactive power setpoints. © 2020 Institution of Engineering and Technology.

Unmanned aerial vehicles (UAVs) are one of the applications of device-to-device (D2D) technology, where two UAVs can communicate with or without the existence of a base station. It facilitates high content delivery, low latency, low cost, and high data rate communication in wireless networks. Despite the aforementioned benefits, an eavesdropping attack is one of the critical challenges that cause interference in UAV communication in the presence of an eavesdropper. To mitigate the aforementioned challenges, we proposed a secure resource allocation for UAV communication in wireless networks. The applied single carrier orthogonal frequency division multiple access (SC-OFDMA) technique utilize the orthogonality feature to provide secure UAV communication in wireless networks. Moreover, a zero-sum game approach is considered to enable the secure and optimal resource allocation for UAV communication. The main aim of the zero-sum game theory is to maximize the communication channel's data rate and secrecy capacity to achieve a secure and optimal UAV communication scenario in wireless networks. Finally, the performance and simulation of the proposed approach are evaluated against the existing random approach in terms of various metrics such as data rate and secrecy capacity of the communication channel. © 2023 IEEE.
