Differential inequalities, crafted to apply aperiodically intermittent SMC, couple with fixed-time stability theory and custom Lyapunov functions to yield sufficient conditions for MNNs’ FxTS. This establishes that the sliding mode manifold can be reached in the fixed-time, underpinning a control strategy that ensures MNNs’ dynamics converge to a specified manifold within the settling time (TST), defining a lower limit for convergence time. Unlike prevailing literature, this research introduces the utilization of aperiodically intermittent adjustment feedback control in tandem with SMC to guide MNNs towards FxTS. In conclusion, two demonstrative examples are provided to showcase the efficacy of the proposed algorithm.</div></div>","PeriodicalId":50658,"journal":{"name":"Communications in Nonlinear Science and Numerical Simulation","volume":"150 ","pages":"Article 108995"},"PeriodicalIF":3.4,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144289915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the energy transfer mechanism of the vibro-impact nonlinear energy sink (VI-NES) in continuous systems, and its consequences in vibration suppression is addressed. We uncovered the significance of a new distinctive energy transfer phenomenon termed inter-modal energy scattering (IMES), which was largely overlooked by most of the investigations concerning VI-NES. Considering a coupled system consists of a cantilever beam and an attached VI-NES, the non-smooth dynamics of the system is first formulated in a measure differential complementarity problem and treated using an energy-conserving integration method. Then the energy transfer mechanisms including the common targeted energy transfer (TET), the IMES, and their coexistence effect, are comprehensively investigated. Finally, the vibration damping performance of the VI-NES for the beam under harmonic force, broadband white noise, and transient shock excitations are also discussed and compared to other types of absorbers. It is demonstrated that the IMES is a distinctive phenomenon that can be realized only in the types of NESs with non-smooth vibro-impacts, to allow a broadband transfer of vibration energy among the eigenmodes of the host beam, resulting in hence a much more effective vibration reduction than the tuned mass damper (TMD) or other NESs.</div></div>","PeriodicalId":50658,"journal":{"name":"Communications in Nonlinear Science and Numerical Simulation","volume":"151 ","pages":"Article 108993"},"PeriodicalIF":3.4,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144289913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When control input fail to meet the prescribed performance requirements, strict monotonicity can lead to constraint failure and singularity problem. This paper proposes novel non-monotonic prescribed performance specifications for tracking control of input-limited nonlinear systems, allowing for customized relaxation of constraint boundaries in cases where input is limited. By incorporating quadratic characteristics into the prescribed performance design, transient input oscillation is effectively suppressed. Coupled with a local asymmetric design, the prescribed performance boundaries impose asymmetric constraints during transients and symmetric constraints during steady-state, enabling effective regulation of output overshoot and preventing any bias in the steady-state tracking error. The proposed scheme, grounded in Lyapunov stability theory, guarantees that all signals within the closed-loop system are ultimately uniformly bounded, with the tracking error compelled to evolve within the prescribed boundaries within the prescribed time. Simulation results validate the effectiveness and superiority of the scheme.</div></div>","PeriodicalId":50658,"journal":{"name":"Communications in Nonlinear Science and Numerical Simulation","volume":"150 ","pages":"Article 109016"},"PeriodicalIF":3.4,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144289909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
