Feedback-based methods combining proportional-integral and/or resonant controllers are the most common option for Active Power Filter (APF) control. Alternatively to classical feedback-based control, state-feedback current control could be used, potentially enabling better dynamic performance. State-feedback current control has been previously proposed for grid-connected converters;however, reference tracking response of multiple harmonic components of the controlled current has not been reported. This is highly relevant to comply with grid codes. This paper analyses the design and implementation of state-feedback current control for harmonic current compensation in APFs. © 2024 IEEE.

For an AI tic-tac-toe manipulator application, a real-time vision-based approach is proposed. The technique employs the RealSense camera to capture color and dept. images. Combining object detection and image processing techniques to identify X's and O's positions on the game board. However, we recognize that errors can occur during object movement when using only 2D images. To solve this problem, a calibration method between RealSense and the manipulator based on the point-to-plane ICP algorithm is presented. This method provides the 3D object position in the robot coordinate, resulting in increasing the accuracy from 86.25% to 97.25%. Our experiment shows that this technique is highly effective and can accurately identify position objects. © 2024 IEEE.

A growing number of works have investigated inferring the topology of networked dynamical systems from observations, such as to better understand the system behaviour. Despite the tremendous advances, most of them require the observations to be abundant. This paper focuses on inferring the topology by injecting single excitation on a node and collecting several steps of noisy observations. The problem is challenging because the noises cannot be depressed in several observations and are mixed with the injected excitation, making it hard to directly reveal the topology. To practice, we develop a probabilistic method based on the hypothesis test framework. First, we infer the neighbors that are within h-hop of the excited node and derive the accuracy guarantees. Then, we extend the method to infer the exact h-hop neighbors. A computable lower bound for the accuracy probability is established to provide confidence support in the inference procedures. Furthermore, we give the conditions of excitation input to ensure a desired inference probability, which provides guidance for the input design. Numerical simulations are conducted to verify the effectiveness of the proposed method. © 2024 IEEE.

Feedback narrowband active noise control (NANC, FBNANC) systems have been developed to suppress sinusoidal noise signals generated by rotating machines such as diesel engines, fans, etc. They do not require any reference sensor and can avoid the frequency mismatch and the acoustic feedback, as compared with the conventional feedforward NANC (FFNANC) systems. In this paper, a modified FBNANC system is proposed which contains three subsystems, namely: 1) a cascade pre-filtered and parallelly updated adaptive notch filter bank (CPANFB) that is included to synthesize the reference sinusoidal signals for the FBNANC controller, 2) an online secondary-path modeling (SPM, OSPM) subsystem that is introduced into the new system to track the secondary-path changes, and 3) a bandpass filter bank that is applied to the residual noise for separating the remaining sinusoids from other broadband noise components, with the former utilized to scale the auxiliary white Gaussian noise (AWGN) for the purpose of reducing its contribution to the residual noise. The three subsystems including the MPA (magnitude and phase adjuster) based controller are seamlessly integrated to work in harmony such that the whole FBNANC system enjoys nice advantages in both convergence and noise reduction performance (NRP). Extensive simulations are conducted to demonstrate and confirm the effectiveness of the proposed system. © ICA *** rights reserved

This paper documented an experience in transiting and improving the load shedding infrastructure in a nickel processing plant (NPP). The motivation of load shedding improvement is the NPP's policy to reduce the carbon footprint by transforming the power generation into an eco-friendly system. As a result, the power system characteristic is metamorphosed. The NPP owned a static frequency converter (SFC) which provides supplemental power when the loss of the main generation. However, the NPP experience SFC failure and ended in a blackout situation. A thorough analysis is presented in this work with several possible solutions. The investigation found that an improvement to the load shedding system is required to prevent SFC being overloaded. A transition scenario between PLC to relay based and its implementation are documented in this paper. © 2022 IEEE.

The graphical models of reflection and transmission electromagnetic wave in thin slab of dielectric is presented in this report. The mathematical apparatus is theory of microwave circuits, signal flow graphs, bounce diagram. This graphical models lead to formulas and analytical models, that are applied to determining the complex permittivity of dielectric materials. The first part of the report deals with the connection between bounce diagrams and signal flow graphs. The bounce diagram is a time sweep of wave reflections from the beginning and end of the line. Upon reflection, the wave attenuates, the losses are taken into account by exponential terms, but the attenuations are insignificant and in some cases they are neglected. The main difference between a signal flow graph graph and a bounce diagram is that the former represents a mathematical structure with vertices and edges, while the latter is a graphical representation of a physical phenomenon that reflects the direction and level of electromagnetic wave reflection from surfaces with different propertiesThe signal flow graphs represent a visual representation of the model. It is convenient to transit from graphical to analytical models. The second part of report considers what will happen if there is a defect in the dielectric sample under study. Two cases are proposed for a defect included in a cascade in the signal flow graph and a defect as a recursion within the pattern of signal flow graph. There are known the bonce diagram for a cable defect, that could be used by us after little upgrading. The cascade connection in signal flow graph was early explored by Ross G.F. and might be helpful. The recursive model remained unexplored. So such problems have to be solved: a bounce diagram with a defect, a transition to a signal flow graph with accounting on a defect from a bounce diagram, than signal flow graph reduction if it necessary and possible, the creation of a analytic model on the base of a signal flow g

Securing Mobile Robotic Networks Against Replacement Attack

IEEE Transactions on Automatic Control 2025年

作者： Li, Yushan He, Jianping Chen, Cailian Guan, Xinping Cai, Lin Shanghai Jiao Tong University Dept. of Automation China Ministry of Education of China The Key Laboratory of System Control and Information Processing China Shanghai Engineering Research Center of Intelligent Control and Management Shanghai200240 China University of Victoria Dept. of Electrical and Computer Engineering BC Canada

The security of mobile robotic networks (MRNs) has been an active research topic in recent years. This paper aims to secure the ubiquitous formation control of MRNs against the replacement attack, where an external robot can replace a formation robot by compromising the communication and physically interfering with the victim simultaneously. To counter this advanced attack, the novel idea of this work is to leverage the physical proximity of the formation shape and the interaction topology among robots for defense design. First, from the physical proximity perspective, we propose the convex neighbor polygon (CNP) to capture the geometric characteristic of the formation robots, and design a CNP-based security mechanism for the robots during the replacement attack. Then, from the interaction perspective, we introduce the indirect controllability to characterize the possibility that the attacker leverages the interaction between robots to deactivate the CNP mechanism, and establish the conditions regarding the topology structure and the attack input to counter the replacement. Finally, based on the obtained conditions, we demonstrate how to design the initiatory topology among the formation robots to enhance the defense performance. Comparative simulations verify the effectiveness of the proposed method. © 1963-2012 IEEE.
