The proposed scheme aims to achieve cooperative modeling and control for orbit maintenance, attitude stabilization and vibration suppression simultaneously. An integrated dynamic model is established using the Absolute Nodal Coordinate Formulation and Lagrangian mechanics, where time-varying coupling terms are preserved to enhance model integrity, contrasting with the reduction and decoupling methods commonly adopted in existing literature. To address the time-varying coupling effect among the orbit, attitude, and vibration degrees of freedom, a parallel layered scheme is proposed to enable joint integrated modeling-control design while avoiding complex dynamic calculations and enhancing control precision. The scheme is directly applicable to the un-simplified time-varying coupling dynamic model. Specifically, within this parallel layered scheme, vibration control, owing to its relative independence, is separated from orbit-attitude dynamics through equivalent dynamic conversion. Consequently, a disturbance observer-based terminal sliding mode controller is developed to stabilize the orbit and attitude with vibration suppression achieved automatically via active feedback mechanism.

Due to external environmental interference, the observers are designed to accurately estimate the state of the network systems. Meanwhile, the impact of cyber attacks on system security is considered. Differing from other studies, MCDSAs in this paper are considered, which present the interference of malicious attacks on the communication topology, observers and controllers. Based on the characteristics of cyber attacks, the model for CDNs with nonperiodic switching topology is established, and the observer-based intermittent control is proposed to achieve synchronization of CDNs. To decrease the network communication frequency and reduce the risk of cyber attacks, a new ETCS depending on estimate states is designed. Then, using Lyapunov stability theory, several synchronization conditions depending on the status parameters of MCDSAs are deduced, which may estimate the allowable ranges for the duration and frequency of MCDSAs. From these theoretical results, it can be observed that the destructive power of network attacks increases exponentially with the increase of attack duration. Finally, from simulation experiments, the availability of the designed controller and communication strategy is verified, which can ensure the synchronization for CDNs with MCDSAs.</div></div>","PeriodicalId":14660,"journal":{"name":"ISA transactions","volume":"158 ","pages":"Pages 50-61"},"PeriodicalIF":6.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To avoid cross-coupling between estimating block-oriented model parameters, a hierarchical identification algorithm is presented by dividing the parameter vector into two subvectors containing the coupled and uncoupled terms for estimation, respectively. To guarantee consistent estimation on these parameters, an auxiliary block model is designed to predict the inner unmeasurable variables of the Wiener-Hammerstein system for computational iteration. Furthermore, two adaptive forgetting factors are designed to accelerate the convergence rates on estimating both coupled and uncoupled parameters. To overcome the issue of initial value sensitivity involved with the traditional recursive least-squares based algorithms for parameter estimation, a particle swarm optimization (PSO) algorithm based on two different excitation signals is given for initial value optimization of the proposed recursive identification algorithm.
