Moving horizon estimation (MHE) is a well-known alternative to Kalman-like filtering due to its superior performance in terms of estimation accuracy, convergence speed, and robustness to poor initial state guesses. However, most MHE methods cope with unknown inputs by introducing a random walk model, which is unsuitable for fast-varying unknown inputs. To address this issue, we propose an unknown input moving horizon estimator (MHE-UI) that does not require any prior knowledge of the dynamic behavior of unknown inputs. To solve the associated nonlinear least squares problem in real time, we develop a computationally efficient Gauss-Newton iterative algorithm by exploiting the block pentadiagonal structure of the resulting Karush-Kuhn-Tucker (KKT) matrix. A numerical case study demonstrates that the proposed real-time MHE-UI algorithm achieves higher estimation accuracy than the unknown input unscented Kalman filter (UKF-UI) and significantly reduces the computational cost compared to the exact MHE-UI algorithm. © 2023 IEEE.

A numerical technique called Simulated Ising Annealing (SIA) uses digital computers to obtain approximations of the ground states of Ising models. The quadratic unconstrained binary optimization (QUBO) problem in combinatorial optimization, which is challenging to solve through exhaustive search, has significant linkages to the Ising model. Therefore, SIA's main objective is to identify a better solution in finite iterations. In order to enhance the performance of the simulated annealing procedure, we adopt a Gaussian augmented Hamiltonian Monte Carlo (GAHMC) method in this study. We contrasted our algorithm with Gibbs sampling and local quantum annealing method. Finally, we discuss its application on QUBO problem. © 2023 Technical Committee on control Theory, Chinese Association of automation.

The present work is dedicated to exploring the potential of Internet of Things (IoT) technology with the aim of promoting a novel application within the realm of civil engineering. Specifically, the research aims to demonstrate the development of a system enabling continuous real-time monitoring of essential structural parameters. Traditionally, the detection of damages and structural failures relied on periodic visual inspections and manual analyses, leading to reactive responses and delayed diagnoses. In contrast, the proposed IoT-based system offers the capability to collect real-time data, enabling early anomaly detection, prediction of potential failures, and informed decision-making regarding maintenance and repairs. The article elucidates the design and implementation of the system, highlighting the integration of sensors, wireless communication devices, and data analysis and processing algorithms, while also presenting test results that showcase the system's effectiveness in detecting subtle changes in critical structural parameters in a controlled environment. © 2023 IEEE.

A large number of sensors and controllers in the micro-grid system transmit signals through the network, however, due to the physical limitations of the network bandwidth and service capacity, data transmission in the network will have delays, packet loss and time disorder, which will damage the performance of the system, and even lead to instability of the system. Therefore, in this paper, the switching fuzzy time-delay micro-grid system is established, and the Fuzzy controller of the micro-grid subsystem is designed according to the PDC method, and the switching law is designed, the asymptotic stability condition of the system is given by using the method of single Lyapunov function and convex combination, and the stability of the system is analyzed. © 2023 Technical Committee on control Theory, Chinese Association of automation.

This study addresses the problem of guaranteed cost fault-tolerant fuzzy control for multiline re-entrant manufacturing systems (RMSs) against stochastic disturbances and workstation faults. Initially, a nonlinear hyperbolic impulsive partial differential equation model is employed to describe the complex and hybrid dynamics of RMSs suffering from unexpected faults within the working stations, and then the corresponding approximation T-S fuzzy model is constructed. In what follows, with the aid of the parallel distributed compensation fuzzy control scheme, the main results of stability analysis and controller synthesis for the closed-loop re-entrant manufacturing control system are derived using a timer-dependent Lyapunov functional with spatio-temporal auxiliary variables. It is found that by means of the proposed fault-tolerant control approach, the RMS can be effectively and robustly driven to a desired production mode with steady feeding and production rates while the upper bound of a quadratic cost function is minimized. Finally, the effectiveness of the proposed control approach is validated through numerical simulations. © 2013 IEEE.

In complex environments like underwater or underground, traditional navigation technologies face limitations due to the restricted penetration of optical and radio signals. Neutrino signals, which have extremely strong penetration capabilities, offer a new possibility. This study explores the challenges of navigation and positioning of covered vehicles and proposes a neutrino-based navigation and positioning technology to overcome the limitations of traditional navigation technologies in complex environments. This research combines reinforcement learning methods and Kalman filters, using the Proximal Policy Optimization (PPO) algorithm to tune the parameters of the Kalman filter to improve navigation and positioning accuracy. In the study, a Kalman filter estimation system model for vehicles in navigation signal denied environment environments was first established, then a navigation and positioning method based on neutrino detection was designed, and finally, a parameter adaptive PPO Extended Kalman Filter (PPOEKF) state estimation method was proposed. Through mathematical simulation and comparative analysis, the research results show that using reinforcement learning methods to tune the parameters of the Kalman filter can improve the accuracy of navigation and positioning, especially in complex environments. © 2023 IEEE.

Over the past decades, topological interface states have attracted significant attention in classical wave systems. Generally, research on the topological interface states of elastic waves is conducted in the lattices with symmetric elements. This paper proposes composite lattices with/without symmetric elements, and demonstrates the realization of tunable topological interface states of elastic waves via parametric *** quantize the topological characteristics of the bands, a modified Zak phase is defined to calculate the topological invariant by the eigenstates for the lattices with/without symmetric elements. The numerical results show that the tunable frequencies of topological interface states can be realized in composite lattices with/without symmetric elements through the modulation of the parametric excitation frequency. The tunable topological interface states can be introduced into the vibration energy harvesting to design efficient and steady energy harvesting systems.

Satellites tend to form a constellation for better performance over a region of thousands of kilometers. However, how to set up the configuration of the constellation is still a challenge for an engineer. This article proposes several statistical-based metrics to evaluate the effectiveness of constellations from the perspective of observation applications. Then, this article proposes a software tool to analyze the metrics of constellations over a target area. Furthermore, this article illustrates the proposed method with the help of a 40-satellite case study. Finally, this article concludes the proposed method and discusses future work. This method of evaluation for remote sensing constellations would help the engineer determine the design parameters of the large constellation. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Insulated Gate Bipolar Transistor (IGBT) are widely used in electric vehi-cles, aerospace and other fields with high reliability requirements. This paper first analyzes its failure mechanism according to the internal structure of the IGBT, and selects the collector-emitter turn-off peak voltage value VCE-p as the characteristic parameter for life prediction;Using the IGBT accelerated thermal aging data set published by NASAPCoE laboratory to extract data to explore the relationship between characteristic parameter VCE-p and junction temperature;The IGBT life prediction model is built on the basis of BP neural network and the analysis results show that the gradient disappears when the model reaches a certain depth and the prediction accuracy is low under small sample data;This paper further proposes an IGBT life prediction model based on residual BP neural network. Multiple residual network modules are superimposed to increase the depth of the BP neural network. Comparing and analyzing the two models with the performance evaluation index, it can be seen from the results that the prediction result of residual BP neural network has a higher accuracy, and also has a better effect when the sample data is small. © Beijing Paike Culture Commu.
